Scope

Diffraction-based PIAACMC simulation / optimization

Uses Fresnel propagation engine ( OptSystProp.c OptSystProp.h ) between optical elements
Computes linear perturbations around current design for optimization
Automatically computes multiple Lyot stop to follow variable conjugation in different parts of the beam
Polychromatic propagations
Fits aspheric PIAA shapes on basis of radial cosines and 2-D Fourier modes

Usage

Scripts to run the software are located within the source code directory:

./src/PIAACMCsimul/scripts/

The scripts can be linked to your working directory by executing the following command:

ln -s $PWD/syncscripts /myworkdirectory/syncscripts

Then, execute in your work directory:

./syncscripts

This will install all required scripts in workdirectory and install any packages required.

Code is composed of a several layers (from high to low) :

Script	Description
runPIAACMCdesign	Top level script ("-h" for help)
run	Main script, calls runopt script
runopt	Optimize a PIAACMC design or run an existing design, calls sim script
sim	calls runPIAACMC script
runPIAACMC	lower-level script calling C-written executable
