Abstract

The application of phase-shifting photoelasticity to real- time dynamic event involves simultaneous recording of the four phase-shifted images. This purpose is realized in this paper by using a special beam-splitting lens called Multispec Imager. The isoclinic and isochromatic parameters for a given time in a dynamic event are determined by using multi-load to phase-shifting technique. A modified median filter algorithm for wrapped phase data is also presented.
