Abstract
A new whole—field isochromatic fringe compensation technique is presented. In the method, the isochromatic fringe pattern is modulated by the carrier using a carrier generator, and the shifting technique of the moire method and the optical filtering technique are applied. Its applications in diesel engine crankshaft and dynamic thermal analysis are introduced.
