Reflective-type digital holographic microscopy using induced self-pumped phase conjugation technique

Abstract

In digital holography, techniques of noise suppression from the perspective of reference arm have been maturely developed. The object counterpart, however, is still in its infancy. Self-pumped phase conjugation technique which involves a BaTiO3 crystal was introduced unto reflective-type digital holographic microscopy to suppress scattering noise derived from the object arm, prior to recording stage. A phase distorter was introduced as scattering source, and signal-to-noise ratio was calculated. Furthermore, induced method was proposed to speed up the response time.
