# Prysm

[](https://travis-ci.org/brandondube/prysm) [](http://prysm.readthedocs.io/en/stable/?badge=stable) [](https://coveralls.io/github/brandondube/prysm?branch=master)

A python3.6+ module for physical optics based modeling and processing of data from commerical and open source instrumentation.

## Installation

prysm is on pypi: ` pip install prysm `

prysm requires only [numpy](http://www.numpy.org/) and [scipy](https://www.scipy.org/).

### Optional Dependencies

Prysm uses numpy for array operations. If your environment has [numba](http://numba.pydata.org/) installed, it will automatically accelerate many of prysm’s compuations. To use an nVidia GPU, you must have [cupy](https://cupy.chainer.org/) installed. Plotting uses [matplotlib](https://matplotlib.org/). Images are read and written with [imageio](https://imageio.github.io/). Some MTF utilities utilize [pandas](https://pandas.pydata.org/). Reading of Zygo datx files requires [h5py](https://www.h5py.org/).

## Features

Prysm features robust tools for modeling and propagation of wavefronts to image planes and MTF. It also features object synthesis routines and a flexible convolution system in support of image simulation. Finally, it contains rich features for analysis of interferometric data.

For a complete list of features, see [the docs](https://prysm.readthedocs.io/en/stable/).

## Contributing

If you find an issue with prysm, please open an [issue](https://github.com/brandondube/prysm/issues) or [pull request](https://github.com/brandondube/prysm/pulls). Prysm has some usage of f-strings, so any code contributed is only expected to work on python 3.6+, and is licensed under the [MIT license](https://github.com/brandondube/prysm/blob/master/LICENSE.md). The library is most in need of contributions in the form of tests and documentation.
