Project description
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))))
system.wavefront_sensors = [ngs_wfs, lgs_wfs]
lo_loop = aotpy.ControlLoop("LO loop", input_sensor=ngs_wfs, commanded_corrector=dm,
commands=aotpy.Image("LO commands", data=np.ones((10000, 32))),
control_matrix=aotpy.Image('LO control matrix', data=np.ones((32, 2, 4))))
ho_loop = aotpy.ControlLoop("HO loop", input_sensor=lgs_wfs, commanded_corrector=dm,
commands=aotpy.Image("HO commands", data=np.ones((10000, 32))),
control_matrix=aotpy.Image('HO control matrix', data=np.ones((32, 2, 8))))
system.loops = [lo_loop, ho_loop]
system.write_to_file("example.fits", overwrite=True)
