A mode locker is a device used in certain types of lasers to generate short pulses of light. In the context of an X-ray apparatus PCB, a mode locker might be used in a laser that is used to generate the X-rays. The mode locker works by introducing a mechanism to modulate the laser beam in such a way that it produces pulses of light with a very short duration. This is typically done by introducing a modulator into the laser cavity, which changes the refractive index of the laser medium in a periodic manner. This modulation results in the production of pulses of light with a duration on the order of picoseconds or femtoseconds. In the context of an X-ray apparatus, the mode-locked laser might be used as a source of ultrafast X-ray pulses, which can be used for a variety of applications such as imaging, spectroscopy, and diffraction. By using a mode-locked laser, it is possible to generate X-ray pulses that are short enough to capture the motion of atoms and molecules in real time. Also for the optical sensors, some X-ray PCBs use two optical sensors for the purpose of detecting X-rays. This is typically done in X-ray imaging systems that use a technique called dual-energy X-ray imaging. Dual-energy X-ray imaging involves taking two X-ray images of the same object at two different energy levels. By using two different energy levels, it is possible to obtain more information about the object being imaged, such as its composition or the presence of specific materials. The two optical sensors in a dual-energy X-ray imaging system are used to detect the X-rays after they have passed through the object being imaged. Each sensor is designed to detect X-rays at a different energy level. The X-ray source is pulsed twice, once at each energy level, and the signals from the two sensors are combined to produce a single dual-energy X-ray image. The use of two optical sensors in a dual-energy X-ray imaging system allows for more accurate and detailed imaging of the object being imaged. By using two different energy levels, it is possible to differentiate between different materials and structures in the object, which can be useful in medical or industrial applications. Overall, the use of two optical sensors in X-ray PCBs enables the development of more advanced and specialized X-ray imaging systems, and helps to improve the accuracy and usefulness of X-ray images.
Inductor diode string looks like a variable LC delay line, diodes are varicap/varactor. Varying the DC bias on the diodes changes their capacitance which changes the delay.
The white part under the square photodiode is a TEC. It's cooled. I believe the sticker is to show that it was x-ray inspected. I don't see anything that would be for x-ray pickup.
That Peltier junction may have saved, in part, the efforts of Elisabeth Holmes and her Edison device. My understanding, her engineers had problems controlling thermal aspects of their sample wells.
If fhe diodes in the string w/ inductors are reverse biased, than they might have being used as varactors ( varicaps) in some sort of multistage variable T filter w/ frequencies passed in dependence of the reverse bias voltage. Some x-ray inspection equipment even use modulators and multi energy xrays to construct an image of the inspected cargo with sufficient visual information on it to sort out objects & materials on it.
You have the control board/Exciter section the first part of the circuit is a comparator circuit possibly lm324 ics the white ics are ballist transformers they take RF and turn it into usable voltage that the comparator uses to control a bias for the RF deck
The inductor diode inductor string looks a lot like the the stuuf that "applied science" used - lambda/4 at about 7mins in: ruclips.net/video/JO_EHceV9sk/видео.html
doesn't say Hologic on it? They had x-ray machines that could detect explosives in luggage. could the back to back detectors be to determine the direction a particle came from?
Why not unsolder the inductor-diode string, reverse engineer it and find out how it works? It might be an interesting episode for people like me who are not very good at analog stuff.
Don't listen to all of these guys guessing!!! That is the secondary control loop-back module for my Dilithium synthesizer which fell of my UFO while flying over CA recently. Whatever you do, don't expose those lens to UV light, That is part of the self-destruct system neatly hidden on that board. 2 seconds of UV and life as you know it will vaporize in a few milliseconds. As all of the technical youtubers on earth now say, do this at your own risk. Now back to Zorpolaris for a new loop-back board and to have the nuts removed to the nut-zo who installed it... ZOOOOOOOOOOOOOOOOOOOOMMMMMmmmmmmmmmmmmmmmmmmmmmmmmm!!!!!

Is that ChatGPT?
The X-ray label is probably from the PCB assembly house as part of a standard QA inspection after SMT assembly.

Possibly from a pulse laser-based eye surgery machine (Lasik etc).
This is a job for xraytonyb!

U7 and U8 have bodge wires. Either repairs, or circuit board error repairs.
NLTL(Nonlinear Transmission Line) for short pulse(fast rise/fall time) maybe?
Hope you can do some yime a follow-up of this video about what it is or how you used it strange components.
I love picking up weird surplus bds and figuring out what they are and what they do. :)
SPAR Aerospace was a Canadian company. Satellite board with stellar alignment systems?
Mode locker could be for some RF-excited laser setup. It samples the laser and controls it.
I noticed that L15 is broken off, likely from the ROHS Solder "connection".
The thermal spokes being present on all vias suggests the board was laid out by a novice Altium user that doesn't know how to manage PCB rules.

You nailed it!
It is part of a wifi and optical gesture toaster called xray toaster.

I wonder if it's SPAR Aerospace? Involved with NASA.
Dental laser evaluation board… Thermo Fischer Scientific?.
Since when are VIAs made so wide you can fit an insulated bodge wire thru it?
Could it be parts for some kind of Rubidium oscillator setup?
Why not unsolder the inductor-diode string, reverse engineer it and find out how it works? It might be an interesting episode for people like me who are not very good at analog stuff.
Nice picture. What microscope are you using? I'm looking for one for my old eyes.
I will be doing a review of the microscope in about 2 weeks: www.amazon.com/gp/product/B0BGN6ZN52
@@IMSAIGuy Thank you.
have you run a geiger counter over it
Could that be a lambda/4 technique as described in the video here: ruclips.net/video/JO_EHceV9sk/видео.html
I was discussing this with a friend and he believes it was the same idea
