Frequency domain interferometer simulation software

Frequency-Domain Optical Simulations
Calculate light field amplitudes and detector outputs in a quasi-static, user-specified interferometer configuration.

Spatial Effects
Model light fields as Gaussian beams, including paraxial spatial deformations such as misalignment and surface roughness perturbatively using higher order modes.

Control Systems
Simulate open- and closed-loop feedback systems including optical, mechanical and electrical elements.
