SuTrA¶

SuTrA, the Simulation Tool foR Adaptive optics, provides 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.
