This fork can by used with python 3.6

To test

• mkdir /tmp/github/
• cd /tmp/github/
• git clone https://github.com/Diti24/opticspy.git
• Add codebase to python path: pip install -e opticspy
• from opticspy.ray_tracing import * The basics is working... New_Lens.add_surface(number=11,radius=177.41176,thickness=7,glass='N-SK16_schott') gives an error to be investigated...

Opticspy is a python module for optics application. I want this for a long time. One reason is I know both optics and python, so why no develop some optics tools? The second reason is that there is not much opensource, easy-to-use optics program module(matlab has great fuctions but do not specify to optics application). I want this could be developed in to a core for a future web application for optics.

Followings are primary opticspy modules:

1. Real ray tracing and Lens Design:

• Example 1: Basic functions introduction

• Example 2: A double gauss lens example

• Example 3: Build a Petzval lens with codev seq file

• Example 4: Build a microscope lens with codev seq file

2. Zernike Polynomial Methods

• Basic Zernike Polynomial Methods

• Zernike Polynomial Fitting Methods

• Orthonormal Rectangular Polynomials

3. Interferometer and Testing Methods

• Basic Interferometer Methods

• Phase shift interferometer and surface rebuild

• Hartmann Test Patterns

4. Wave Propagation and Aberration Methods

5. Lens aberration, Jones matrix and gauss beam methods

There are some interesting derivative from opticspy:

1. A Zernike Polynomial GUI app based on opticspy and PyQt5

It is very easy to reuse or "wrap" opticspy module with a GUI(e.g. PyQt)

2. Zernike Surface gif show

This is the Opticspy project page

This project is hosted on github in https://github.com/Sterncat/opticspy

Installing

Use pip install (recommend)

$ pip install opticspy

Or download here

$ python2.7 setup.py install

Some trouble shooting please read troubleshooting.md

How to use

>>> import opticspy

And just have fun with it!

What I want

• 1. After import the module and you will get some functions that can do some calculation and education in optics
• 2. Parameters should be very flexible, and the results should be shown in visualized, intuitionistic figures.
• 3. After development of core, I want it be dynamic web application(with Javascript)
• 4. I even hope one day it will become a part of online optics design application, who knows?
