Varying beam profiles #16

Closed Cam-Sim closed 5 months ago

Cam-Sim commented 1 year ago

Currently, pointing loss is determined by a function built-in to the telescope object. This assumes that beams are gaussian. However, other kinds of beam with other intensity distributions are possible and will have slightly different pointing losses for the same rms jitter.

Therefore, some method of implementing different intensity distributions (e.g. flat-top beams) will be necessary. Most notably for modelling the downlink beacon from the satellite, which has a flat-top intensity distribution.

Different beam profiles for beacons are implemented in commit 221c4c35ee7bd79067696dc3097cb7881507fa45.

It is not clear whether varying beam profiles should be supported by the QKD link
