PROGRAM:
NAME
yao - Adaptive Optics simulation tool in yorick
SYNOPSIS
Start yao with the gtk GUI:
yao parfile.par
yorick -i yaopy.i parfile.par
Within yorick (no GUI, but same graphical output)
#include yao.i
aoread,"parfile.par"; aoinit; aoloop; go;
DESCRIPTION
Yao is a monte-carlo simulation package for adaptive optics. It includes fast core coded
in C (e.g. wavefront sensing) that are glued together by yorick interpreted code. One
defines the system to evaluate using a configuration file, and then run aoread, aoinit and
aoloop. Yao features:
* Shack-Hartmann and Curvature WFS, on or off axis.
* Stackarray (piezostack), curvature (bimorph), modal (zernike) and Tip-Tilt deformable
mirrors are supported. The altitude of conjugation is adjustable.
* An arbitrary number of WFSs and DMs can be selected, with the possibility of mixing
types. It is therefore possible (and easy) to simulate single DM systems, as well as
single non-zero conjugate, GLAO and MCAO systems.
* It supports Natural and Laser Guide Stars (or a mix), WFS with photon and read-out
noise.
* It uses a multi-layered atmospheric model, with geometrical propagation only.
* The loop execution has been optimized for speed: the critical routines have been coded
in C. Yorick is thus used as a convenient glue between lower levels optimized C calls.
Overall, this is rather efficient: A simple 6x6 Shack-Hartmann system runs at up to 650
iterations per second on an apple dual 2GHz G5 (200 iterations/sec for a full
diffraction propagation model). A 50x50 Shack-Hartmann system runs at about 3
iterations/s. A 188 curvature system runs at 25 iterations/s.
* Straightforward scriptability to probe parameter domains.
* GTK GUI to change some of the system parameters while the loop is running (new in
v4.0). This provides an educational approach to Adaptive Optics (newbies can play with
the parameters and immediately sees how the system reacts) and can also provides a
quick way to investigate the stability conditions for a newly designed system, before
entering more serious Monte-carlo simulations.
