Hi, I think this video is about 3d imaging, but for inline (Gabor) holography, many text book assumes the object is a plane which is represented as the transmittance coefficient t(x,y), as you can see it is 2D. So My question is that can we get a 3d imaging for Gabor holography? Especially, suppose we have reconstructed the wave/light for a Gabor holography, can we see the images in different views?
Thanks for this interesting question. I think it is best answered by a direct quote from Gabor himself [GABOR, D. A, New Microscopic Principle. Nature 161, 777-778 (1948)]: 'One must expect that looking through such a properly processed diagram one will see behind it the original object, as if it were in place. [...] It is a striking property of these diagrams that they constitute records of three-dimensional as well as of plane objects. One plane after another of extended objects can be observed in the microscope, just as if the object were really in position.'
Hi, there may be a typo at 48:43, the expression in the bottom right purple rectangle should be exp(-2 PI i K.X) instead of exp(-2 PI i K.x).
Yes, you are right. Thank you for pointing this out. I'll add this correction in the video description.
This is excellent - Thank you for making this material public. You have made amazing lectures, that i love to revisit when in doubt.
Thats amazing! Thank you, great lecture, helped me to better understand holography princples

Hey sir I have a question can you help me please?
