kandi X-RAY | lightpipes Summary

lightpipes is a Python library. lightpipes has no bugs, it has no vulnerabilities, it has build file available and it has low support. However lightpipes has a Non-SPDX License. You can install using 'pip install lightpipes' or download it from GitHub, PyPI.

LightPipes is a set of functions written in Python (Before version 2.0.0 these functions are in C++). It is designed to model coherent optical devices when the diffraction is essential. We put the C++ based version of LightPipes in another repository: opticspy/clightpipes. The pure Python version is as fast as the C++ version due to the use of the numpy, scipy and pyFFTW packages. The toolbox consists of a number of functions. Each function represents an optical element or a step in the light propagation. There are apertures, intensity filters, beam-splitters, lenses and models of free space diffraction. There are also more advanced tools for manipulating the phase and amplitude of the light. The program operates on a large data structure, containing square two-dimensional arrays of complex amplitudes of the optical field of the propagating light beam. The LightPipes routines are modifications of the LightPipes C routines written by Gleb Vdovin for Unix, Linux, DOS and OS2 workstations. Visit the website of Flexible Optical: where you can find the source code of LightPipes and a manual.

2d Fourier Transforms: FFT vs Fourier Optics

QUESTION

2d Fourier Transforms: FFT vs Fourier Optics

Asked 2021-Apr-18 at 21:01

I am trying to use programming to increase my understanding of Fourier optics. I know that physically and mathematically the Fourier transform of a Fourier transform is inverted -> F{F{f(x)} = f(-x). I am having two problems 1) The second transform doesn't return anything like the original function except in the simple gaussian case (which makes it even more confusing), and 2) there seems to be some scaling factor that requires me to "zoom in" and distort the transformed image to a point that it is much less helpful (as illustrated below). **Editted with suggestions from @Cris Luengo

...

ANSWER

Answered 2021-Apr-18 at 21:01

After chatting with Cris, it seems that there is no scaling factor, this type of DFT just works this way it seems. So the solution I have found is to increase the pixels to the point that I can zoom in and have a clear enough image. It's not a great solution but paired with LightPipes it is now possible to get an idea of what the transform of light modes will look like, as well as illustrate that at the image plane of a lens system they will appear as they did in the front focal field.
