Phase retardometer: a proposed device for measuring phase retardance.
Phase retardometer: a proposed device for measuring phase retardance.
The realization of a standard device for measuring phase retardance has been retarded by the lack of a simple underlying physical concept that can be formulated in a simple mathematical expression to provide quick, direct, and accurate results. A proposed device that meets these requirements and simple formulas for retardance measurements are presented.
