Hi David,

Thanks for the response.

Couple of reasons:

The image simulation with specific sensor settings take a lot of time. The goal is to generate at set of images for multiple tasks, object detection being one of those.

If I can generate the PSF distribution, I can use python to quicken the process (or so I assume). With that I can generate larger dataset for a statistical analysis.

In the end, approaches like machine learning would need large datasets which becomes difficult with the time image simulation takes and there are no other ways that I could think of, to produce images that would be a close reprensatation of how the output of the lens would be.

Best,

Amit

Hi Andrey,

I was thinking of that, hence the creation of field point grid. But i was wondering if there was a more elegant way of doing that. I was more intrigued by this question because if there is a “MTF Map” option that can be calculated there should be a PSF Map somehow being calculated in the background.

Thanks,

Amit

But that would just give a qualitative estimation of the PSF.

I want PSF data (as in the intensity distribution as a txt file) so that i can later use it to convolve image in python and produce output same as the image simulation process in ZEMAX. This because, the image simulation process in ZEMAX is slow and generating large datasets would be very difficult.

Do you mean a script for generating PSF from different field points? I have such a script for extracting the PSFs for different field point. Then i have to combine them and form the PSF distribution over the image plane (all in python).

Or do you mean a script for image simulation and translating it to a txt?
