jcranney/recon-simu

Hardware simulator for SCAO reconstruction

For the first version, the Reconstructor will take open-loop slopes, as provided by the Hardware Simulator, and compute the reconstructed phase, which will be compared to the true phase by the Performance Monitor.

Loading

Setup

Install the Python requirements with:

pip install -r requirements.txt

Running

Launch these 3 processes in separate shell sessions.

### Shell session 1
python src/hardware_simulator.py

Wait for the above call to start displaying a timing output like: rms wf: 0.6607 um: : 1814it [03:28, 10.52it/s].

Then, launch the reconstructor script:

### Shell session 2
python src/reconstructor.py

Again, wait for that to produce a timing output, then launch:

### Shell session 3
python src/performance_monitor.py

The reason for waiting is to give the programs time to write to shared memory before calling them from another program.

Modifying

The Hardware Simulator and Performance Monitor are built, but the Reconstructor currently estimates all zeros. You can replace the function def reconstruct_phi(slopes): in the reconstructor.py file with a working reconstructor.
