What is the Pupil Shift The Ray-aiming algorithm is robust and can correctly aim rays for most aberrated and/or decentered/tilted pupils. However, it needs to first find a ray that reaches the stop surface in order to iteratively find the desired stop coordinate.  By defa...

Introduction Geometrical ray tracing is an incomplete description of light propagation. Strictly speaking, the propagation of light is a coherent process. As a wavefront travels through free space or optical medium, the wavefront coherently interferes with itself. Modeling...
