OPTICAL DELAY GENERATOR AND SPECTROSCOPIC APPARATUS INCLUDING SAME

원문 (중국어)

An optical delay generator includes a polarizing beam splitter configured to split an incident beam by reflecting or transmitting the incident beam depending on the polarization state, a rotating polygonal mirror configured to reflect the incident beam reflected from the polarizing beam splitter to provide a first reflected beam, a micromirror array configured to reflect the first reflected beam and configured to provide a second reflected beam back to the rotating polygonal mirror, and a phase delay member between the polarizing beam splitter and the rotating polygonal mirror, wherein the polarizing beam splitter is configured to provide an output beam by transmitting a third reflected beam provided by reflecting the second reflected beam from the rotating polygonal mirror, and the output beam has an optical delay difference with respect to the incident beam.
