Abstract: |
A feedback interferometer of quasi-copath micro-plate laser consists of micro-plate laser lens and beam splitter set on axle of emission end in sequence two acousto-optic frequency shifters, light block plate, focusing lens and reference reflector set in sequence on transmission light path of beam splitter photoelectric detector and two sine signal generators set on reflection light path of beam splitter reference electric signal generating circuit and two orthogonal phase sensitive detectors. |
