Abstract

A phase-shifting interferometry (PSI) using a multi-longitudinal-mode blue laser diode was developed. Since the longitudinal modes of a laser diode are located almost at even interval and changes synchronously with the injection current, by setting an optical path difference between two arms of an interferometer in such a way that makes the contrast of interferogram to be a maximum, the phase shift required for PSI can be obtained by changing the injection current. Moreover, in such a condition, the PSI system works even mode hops occur. Theory and experimental results for measuring the transmitted wavefront of an aspheric DVD pickup lens are presented.
