Heterodyne polariscope for measuring the principal angle and phase retardation of stressed plastic substrates

•An innovative heterodyne polariscope was introduced.•It is capable of measuring the full-field principal angle and phase retardation of stressed substrates.•Its validity and feasibility were verified using experimental results.•The errors of the measured principal angle and phase retardation did no...
