ray tracing

An analysis technique by which multiple rays emitting from a point source are drawn through an optical system. Principal and marginal rays are used to simulate how an object on a sample plane is transformed by an imaging system, and projected onto an image plane.

Geometrical Construction of Ray Diagrams

A popular method of representing a train of propagating light waves involves the application of geometrical optics to determine the size and location of images formed by a lens or multi-lens system. This tutorial explores how two representative light rays can establish the parameters of an imaging scenario.
