Is there is a way to build an image simulator in Matlab from zemax ?

Sure... you can use the ZOSAPI to communicate back-and-forth between Matlab and Zemax OpticStudio.

You can access all the analyses in OpticStudio from Matlab.  You can:

  • Simulate images in OpticStudio and display in Matlab
  • Collect PSFs across the FoV and compute your own image simulation
  • Use the MTF for systems where the PSF / MTF are constant over the field and use linear systems theory to compute the image

What do you want to do that is beyond these options?

Hi Brian,

Thanks a lot for the info & this is exactly what I need. Do have any resource material/any example of thread where the following topic is explained:

  • Collect PSFs across the FoV and compute your own image simulation
  • Use the MTF for systems where the PSF / MTF are constant over the field and use linear systems theory to compute the image

Looking forward towards your reply,

Kind regards,

saikat

Hello,

 

Thanks for your posts here on the forums!

 

 

Saikat, as Brian mentioned, this is all possible from the ZOS-API. If you would like to learn more about the basics of the ZOS-API connection, I would recommend to check out this learning path:

You may find complete examples, for example about how to pull the FFT MTF data, in the ZOS-API Syntax Help:

You may find further references and sample codes at these forum threads:

I hope this helps, but if you have any further questions, we will be happy to help!

 

 

Best,

Csilla
