Abstract

A novel method of coherence microscopy with a grating-generated delay line is demonstrated to produce depth-lateral images without axial or lateral scanning. A new image-reconstruction approach based on random phase modulation of the reference beam is realized. The depth-lateral reflections of test objects are digitally reconstructed with a simple algorithm.
