Dear Mr. Wang,

for example :

http://www.ibm.com/developerworks/ru/library/l-signals_perl_4/

For understanding the algorithm this site is good, if you need to make simple software.

Unfortunately, this page in another language then English, but software for Fourier hologram is represented on Perl and has clear figures.

You can find "digital holography or filters" on wiki or in google, etc.

If you have any questions you can send me e-mail.

Best regards,

Pavel Yezhov. 

Thank you very much. I will contact you if I have some questions.

Dear Mr Wang,

A free access software is available from:

A very nice book is "Introduction to Modern Digital Holography With Matlab".

http://www.cambridge.org/ve/academic/subjects/physics/optics-optoelectronics-and-photonics/introduction-modern-digital-holography-matlab

Myself, I use python instead Matlab and translation is very easy. Holopy is a free python library for digital holography:

Hello,

I would like to recommend two books:

- Numerical Simulation of Optical Wave Propagation with Examples in MATLAB

- Computational Fourier Optics: A MATLAB Tutorial

You may find them useful for implementing general propagation functions, sampling requirements, minimum/maximum propagation distances, etc.

If you are looking for something like Matlab but don't want to spend the money, you may have a look at Octave. That is a OpenSource clone of Matlab. Almost all commands are identical.

I have been using MATLAB for computer generated holograms and diffractive optics design. For a beginner MATLAB is good and easy to start. You will get a lot of tutorials and codes from mathworks. But as you had mentioned MATLAB is not free. One option is to use python. It is free and is very similar to MATLAB. At present I also plan to shift to python for the same reason. Another option is to use scilab. We have option to convert matlab codes directly to scilab also. The codes are very similar.  

The best MatLab code codes for digital holograms simulation are in:

Thank you very much for all the help !
