Abstract

See full text

An apparatus for generating holograms includes a laser source configured to emit a laser beam with a frequency of v; an acoustic optical modulator configured to generate, from the laser beam, a first beam with a frequency of v1 and a second beam with a frequency of v2; a first beam splitter configured to split the first beam into a first reference beam and a first object beam, the first object beam being led to a sample; a second beam splitter configured to split the second beam into a second reference beam and a second object beam, the second object beam being led to the sample; and a detector configured to detect an image composed of a first fringe, based on the first reference beam and the first object beam, and a second fringe, based on the second reference beam and the second object beam.
