Abstract
Phase-shifting techniques have been successfully implemented to yield the phase fi om sinusoidally modulated intensity fields in interferome try. However, when the intensity fields are that of squared sinusoidal modulation, as in the case of photoelasticity, implementation of exis ting phase-shift operations will result in error. An operation is outl ined to derive faultlessly the phase in computer-aided photoelasticity .
