Abstract

See full text

A real-time birefringent imaging spectrometer based on differential structure is provided. A polarization beam splitter to add an imaging branch is set. Meanwhile, the structure alters the conventional optical structure to the differential structure by setting another polarization beam splitter. Taking the difference between these two interferogram obtained by two branches of differential structure as the final interferogram and performing the required post-processing calculations produces the spectrum at each pixel. Common-mode error is intensively restrained due to the differential structure, and 50% of the optical loss is avoided because of casting off the analyzer; a high spatial resolution, high spectral resolution image is acquired by combining the high spatial resolution, colorful image with the low spatial resolution, high spectral resolution image.
