Hi Sebastien

Thank you for the reply. Yes, You are right, we can divide the problem to two off-axis hologram. I think you can wait as I think I have found the solution. I will come back with a short description of my solution!!

I will send that paper that describes my work to you as well.

Best regards,
Davood

Hi all

I am working on digital holographic shape measurements based on speckle metrology. Mostly with single shot dual-wavelength methods to be able to measure moving objects. Recently I have started to work on the calibration part. Here you can see, one of my related papers:
www.tandfonline.com/doi/full/10.1080/155....942932#.VFySiPnF-tY

Since I want to have a simulated single shot dual wavelength holographic data to check my calibration algorithm, I am in a need to change the provided MATLAB code by Sébastien in a way to have dual-wavelength. Here the important issue for me is having two spherical reference waves with different angle of incident. Also to produce speckles in relation to Numerical aperture. (In the existed code that shared by Sébastien) the frequencies are controled by Gaussian filter while I want to control by Numerical aperture!! I emphasized on spherical reference wave, because I am going to do the system telecentric. Then I need to know that if my by calibration algorithm will be able to remove the effect of spherical reference waves or not. Telecentricity is important as we are working with some algorithms that always use wave propagation! while we are in a need for constant magnification.

PS: Let say we have an image with 10001000 pixels. Then I am interested to have small effect of spherical reference waves on all pixels.

Thank you very much
