Welcome to the official Photon Simulator (PhoSim) repository!

PhoSim is a set of extremely fast photon Monte Carlo codes that calculate the ab initio physics of the atmosphere and a telescope & camera in order to simulate realistic optical/UV/IR/X-ray astronomical images. PhoSim can also simulate any optical system that produces images (e.g. cameras, satellites, human eye).

The complete site for all PhoSim information and documentation is not here, but is at https://www.phosim.org
