aotpy

Helper Python package for handling Adaptive Optics Telemetry (AOT) standard files. Basic documentation available.

How to install

Support is offered for Python 3.10 or later.

From PyPi (recommended)

python -m pip install aotpy

From the repository

Clone the repository and then install with:

python -m pip install path/to/aotpy

where 'path/to/aotpy' is the path to the root of the cloned repository.

Code example

import numpy as np
import aotpy

system = aotpy.AOSystem(ao_mode='GLAO')
system.main_telescope = aotpy.MainTelescope("Example telescope")

dm = aotpy.DeformableMirror("Example DM", n_valid_actuators=32, telescope=system.main_telescope)
system.wavefront_correctors.append(dm)

ngs = aotpy.NaturalGuideStar("Example NGS")
lgs = aotpy.SodiumLaserGuideStar("Example LGS")
system.sources = [ngs, lgs]

ngs_wfs = aotpy.ShackHartmann("WFS1", source=ngs, n_valid_subapertures=4,
                              measurements=aotpy.Image("NGS slopes", data=np.ones((10000, 2, 4))))
lgs_wfs = aotpy.ShackHartmann("WFS2", source=lgs, n_valid_subapertures=8,
                              measurements=aotpy.Image("LGS slopes", data=np.ones((10000, 2, 8))))

                            control_matrix=aotpy.Image('LO control matrix', data=np.ones((32, 2, 4))))
