COMPASS

YoGA is a plugin for Yorick built on top of NVIDIA's CUDA toolkit. It provides GPU acceleration from within the Yorick environment for a number of applications (Fourier transform, matrix operations, random number generation, etc ..).

YoGA_AO is an extension to the YoGA plugin for Yorick, providing efficient tools to simulate a wide range of adaptive optics systems at various scales. General software design has been inspired by YAO, a simulation tool developed by François Rigaut. Main features include :

• on-line multiple layers Kolmogorov turbulence generation at various altitudes
• multi-directional raytracing through turbulence
• multi-directional Shack-Hartmann (SH) spots computation using either natural or laser guide stars
• centroiding on SH spots using various algorithm : center of gravity (COG) , weighted COG, thresholded COG, brightest pixels COG
• Least square command strategy
• Realistic piezostack deformable mirror model

The following wiki pages will guide you through the installation and use of the simulation tool.
