Chao Wen Liang, Jose Sasian

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review


This method uses a DMD chip to generate a sinusoidal grating as the light source and uses a slit modulating light at the image location. The transverse ray aberration function is obtained through phase shifting.
