OPTICAL DELAY

A system for varying a delay of an optical beam has a rotatable wheel and a set of one or more prisms mounted about a circumference of the rotatable wheel. The set of one or more prisms are positioned to retroreflect the optical beam that passes approximately tangent to the rotatable wheel to cause...

Summary:A system for varying a delay of an optical beam has a rotatable wheel and a set of one or more prisms mounted about a circumference of the rotatable wheel. The set of one or more prisms are positioned to retroreflect the optical beam that passes approximately tangent to the rotatable wheel to cause a delay or phase shift to the beam as the rotatable wheel rotates.
