Simulation of AO residuals through phase PSD budget

AOPERA

Adaptive Optics Psf Estimation and Residuals Analysis

This package runs fast computation of adaptive optics (SCAO) residuals. It provides the following outputs:

• PSD of the electromagnetic phase (in rad2.m2) for each AO error term,
• AO error budget (integral of the PSD),
• long exposure PSF at any wavelengths,
• short exposure PSF at any wavelengths,
• fiber coupling efficiency.

AOPERA is particularly designed to manage Fourier Filtering wavefront sensors, such as the pyramid (but any FF-WFS can be implemented), in single conjugated AO (SCAO) mode. The code deals with the sensitivity of FF-WFS and manages non-linearities through the convolutive formalism (Fauvarque PhD thesis).

AOPERA is compatible with TIPTOP ini files in SCAO mode.
