Integrated polarization interferometer and snapshot spectropolarimeter using the same

摘要

An integrated polarization interferometer and a snapshot spectropolarimeter applying the same are provided. An integrated polarization interferometer according to an embodiment of the present invention comprises: a polarization beam splitter for separating an incident complex wave; and a first polarization attached to a first surface of the polarization beam splitter and transmitted through the polarization beam splitter And a second mirror attached to the second surface of the polarizing beam splitter and reflecting the second polarized light reflected by the polarizing beam splitter to the polarizing beam splitter. . This makes it possible to perform snapshot measurement of the spectral polarization phenomenon that is resistant to disturbances due to external vibration and the like using the integrated polarization interferometer, and to improve the repeatability and accuracy of the measurement.
