Din, if it’s a mirror with a focal length what’s the focal length formula then? Do I have to put my picture within focal length to avoid blurry image? How to increase the focal length of that mirror?

I used setup2 with 532nm coherent laser and I removed the lens from the laser module to get the beam expanded and I got some pretty good results as shown below Setup2.JPG I'm using a regular white flash light for image construction and the image looks good with high detailed resolution However when ...

Hi Din, So from my understanding Setup1 give more control on the beam width because you mentioned we can add beam expander at any point, does this means we have more control on the reference beam ratio to the object beam ratio which have to be 3:1 or 4:1 for holography ? -Yes I was asking about the ...

Hi, I'm trying to get a holographic setup to simulate a reflection HOE for an actual reflection mirror (not an image of a mirror) an actual flat mirror specs. I'm using 532nm (green) laser as test & Incident beam should be 60degree from normal of HOE and the reflected beam is 0degree to normal a...
