Image fidelity improvement in digital holographic microscopy using optical phase conjugation

摘要: With respect to digital holography, techniques in suppressing noises derived from reference arm are maturely developed. However, for the object counterpart not being well Optical phase conjugation technique was believed be a promising method this interest. A 0°-cut BaTiO3 photorefractive crystal involved self-pumped scheme, and employed in-line holographic microscopy, both transmission-type reflection-type configuration. On pure physical compensation basis, results revealed that image fidelity improved substantially with 2.9096 times decrease noise level 3.5486 increase ability discriminate on average, by scattering prior recording stage.
