Sagnac Interferometer

Application ID: 60061

This is a model of a simple Sagnac interferometer consisting of two mirrors and a beam splitter arranged in a triangle. The entire modeling domain rotates; as a result, the rays propagating in opposite directions in the triangle have different optical path lengths due to the Sagnac effect. This can be used to deduce the angular velocity of the system.

This model example illustrates applications of this type that would nominally be built using the following products:
