Hey Madison, The Slide Surface in sequential mode and Slide Object in non-sequential mode will allow you to import a bitmap image and then pass rays through it. Note that it is the intensity of the rays that is modulated by the bitmap, not their phase. Mark How to get the phase modulated then? Suppose i want to reconstruct a phase CGH by illuminating it with rays in zemax. can that be done?
I have developed a system in NS mode where I am attempting to do 2D pupil expansion by using multiple re-directions and extractions. I am using segments of hologram lens placed adjacent to each other with varied diffraction efficiency (by calculating refractive index modulation for particular DE using Kogelnik’s theory). Despite using the theoretically calculated values, I am unable to get uniform output on the detector after the exit pupil. I am using ray splitting with rays having much lower minimum intensity. As you said for EPE DLL should be used. the pupil is expanded in my system but the intensity is not coming out to be uniform. Can uniformity be achieved in my system? or i have to use DLLs. I wouldn't prefer the latter system because it seems bit complicated to me.
How do you do the Diffraction efficiency analysis here?if these are volume holograms i should be able to see the wavelength and angular selectivity plots. Also, i should be able to vary refractive index modulation values so that i can vary diffraction efficiency for achieving uniform intensity in exit pupil. How does your model support that?
Thank you. Can you provide me link of any available article for optimization in non-sequential mode for collimation?
HOW CAN I OPTIMIZE THE LENSES IN NON-SEQUENTIAL MODE WHEN I HAVE DESIGNED THEM FOR A SIMPLIED SOURCE IN SEQUENTIAL MODE?
Thank you so much! This was very helpful
been one year since somebody reported it, still no changes have been made to the article. i am having the similar issues. I would like to add that the article seems incomplete as it doesn’t actually end with final abberation free lens. Please see to this... when i changed ofh back to standard surface, it became what it initially was. what was the point of article then?
