Some flat earthers bought a bunch of ring laser gyroscopes only to have them report the earth as spinning at around 15 degrees per hour. They thought they were all broken despite spending around $15,000 on each.
They not only can “sense” it. They can measure it such that they can determine earths rotation axis with respect to its baseplate to within fractions of a degree
I'm a geophysicist I work in airborne gravity surveys, the gravimeters we use in aircraft to measure gravity have several fibre optic gyros in them, they detect the slightest rotation of the gravimeter and this data is used to control a motor driven gimbal system which the actual gravity meter is mounted in, the gyros detect and along with the motor driven gimbles keep the gravity meter orientated correctly so it measures only the vertical component of gravity as much as possible.
@Nevir202 Mapping areas of low and high gravity, using the contrasts in gravity to map crustal structures, often we are mapping low gravity areas, gravity is proportional to mass, lower density rock has lower mass per volume so gravity is slightly lower where crustal rock is lower density, sedimentary basin deposits that can host or be the source of oil and gas deposits are low density so are of interest to oil and gas exploration companies.
I locked this type of technology by a few months and I never found, if check on RUclips or google information about gyroscop you find just classic mechanic gyro. Thanks for video
We put one of these on top of a vibro-replacement probe, and it was used to project the GPS position of the probe's top down to the seafloor. It worked very well.
Have you came up with the idea of using light for this purpose? Not this but it has happened to me multiple times, i got a great idea, just opened youtube and boom, someone has beaten me to it. And i get deflated then
"Compared to the mechanical system, it consumes little energy " With all due respect, what are you talking about ?! Does something that does not require battery power consume more than lasers and their control systems ?!
@@yakut9876the mechanical gyros are multiple motors spinning continuously, and a diode laser is like a single Watt. So yeah, absolutely less power for FOG.
How do they make the fiber optics in FOGs durable? Usually fiber optics are prone to breakage if you bend it (cannot go below specified bend radius), so I would imagine vibrations from moving vehicles, shock from sudden large accelerations, pose a problem.
IMU measures more axis: It's an accelerometer, gyro and magnetometer. This is "only" a gyro, though the tech could be used to measure acceleration using for example a triangle, with more calculations required to isolate the different axis (unless a easier hack exist which is well possible as i didnt search).
Different manufacturers want to differentiate their products from another. One calls it Ring-Laser, the other Fiber-Optic. My little company calls it Laser-Optic-Ring-Fiber (LORF). 🤪

( Wear, vibration, friction, temperature changes ) These are mechanical problems that have been solved, so stop exaggerating matters. By the way, they are all present in the electronic system that controls and operates the light. With regard to wear, any material is susceptible to wear and tear, and any system is susceptible to wear, regardless of the type of system. All materials and devices/hardware are consumed little by little until they expire completely and fail as a result of electrons ( electricity ) passing through them. The most famous example is electric heating elements, It is even easier to heat by gas. Regarding vibrations, the optical and electronic systems have noise and vibrations and electrical transformers are the most famous examples of this. As for friction, it is also present in electronic devices, and this results in heat loss and also electrical decomposition of the material. Regarding temperature changes, they pose a danger to electronics, as it is known that heat and electronics are enemies. The same can be said about water and electronics, they are also enemies, and humidity can cause corrosion and paralyze the entire system. We should also not forget the problems of electrical insulation breakdown that occurs in capacitors or even batteries, and electromagnetic pollution, which is a silent killer. Add to that the attenuation that occurs in the optical system and its sensitivity to heat and radiation, as it requires special treatment and constant cooling, and it is also a voracious consumer of electricity.
I think it's a little disingenuous to say it's "measuring the difference in time" when it's not . . . what it's measuring is the interference pattern which is a result of the effective path length change. Measuring deltaT would require electronics working faster than the speed of light . . . (yes, you do show this in the diagrams, but it's not what you say . . . I would think one of your engineers would be as adamant of correct terminology and phrasing as some random dude on RUclips)
Path length and time are connected, does it matter how it's measured if you can calculate one from the other? It's like saying "they can't measure rotation because they're just measuring path length differemces". One follows from the other, so it's effectively equivalent.
@@electrowizard2000 yes, it does matter. Try to get any merit in a scholastic environment with that attitude . . . Have you ever heard of a thesis defense? I’d love to peer review your papers . . .

A technology other than the laser can be used to measure this, but the laser has bright, shiny lights, so it is promoted in the media by non-specialists.
New technologies, new research tools Let me suggest for schoolchildren and students on one's own to measure the Universe, dark energy, black holes, etc. To do this, I propose two practical devices. «laser tape measure *+reference distance* 1,000,000 m”» and «Michelson-Morley HYBRID Gyroscope». I am writing to you with a proposal for the joint invention of a HYBRID gyroscope from non-circular, TWO coils with a new type of optical fiber with a “hollow core photonic-substituted vacuum zone or (NANF)” where - the light travels 500000 (In a laser tape measure, the length of the optical fiber is fixed at 1000000 ) meters in each arm, while it does not exceed the parameters 94/94/94 cm, and the weight is 94 kg. Manufacturers of “Fiber Optic Gyroscopes” can produce HYBRID gyroscopes for educational and practical use in schools and higher education institutions. Einstein dreamed of measuring the speed of a train, an airplane - through the Michelson-Morley experiment of 1881/2024, and only then would the experiment be more than 70% complete. This can be done using a fiber optic HYBRID gyroscope. Based on the completion of more than 70% of Michelson's experiment, the following postulates can be proven: Light is an ordered vibration of gravitational quanta, and dominant gravitational fields adjust the speed of light in a vacuum. you can make scientific discoveries; in astronomy, astrophysics, cosmology, higher theoretical physics,...
@@nick76dune Yup, but CNC is much more demanding than: A laser A half silvered mirror. Fibre optic cable. A line array camera Low speed, low transistor count semiconductor. The principal of operation dates back to experiments from 1917 ish, so the science is global knowledge.

Why do you always have to Attack other techniques just to prove that your technique works? A successful technique carries with it its meaning and does not need to be challenged with other techniques to prove it. “Moving parts are subject to breakage and wear.” This phrase often comes from uneducated or non-specialized people, but the educated, specialized person says that everything has a certain design life and has limits under certain conditions, meaning that nothing is perfect, including the electronic system that always They promote it, imagine that my electrical heating elements need to be replaced every few months, imagine that my Internet router was once found not working because it was covered in dust even though those things are, as they say, "solid state." Everything can be subject to breakage, failure, and a certain service life, and this is not limited to “moving parts,” so it does not matter if it is a “solid state” or a fluid state. It is better to let matters be dealt with by their compatible systems. Vital problems are dealt with by the biological system, electrical/electronic problems are dealt with by the electrical/electronic system, and mechanical problems are dealt with by the mechanical system.
I used to fly with and operate a Litton Inertial Nav Unit (INU). They failed often enough from all those inherent mechanical problems. They have never been fixed, just improved over time to reduce the time between failures. The optical gyro is the solution to "fix" all the mechanical problems. The mechanical gyro system requires a long initialization before flight along with other preflight precautions. The optical gyro is the fix for the initialization "problem" that was not solved. That old massive Litton INU was decent in its day but the optical system is way more "perfect".

Just out of curiosity.

I don't have first hand experience, but compared to a mechanical system this would have to use a tiny amount of energy.

Once coiled up, the fibers in a gyro could be encased in epoxy or whatever. The fiber coils are not spinning like a mechanical gyroscope.

Way better specs, by several orders of magnitude.
Still not as good as an a HRG, but they wouldn't even give me a quote for one of those lol.
