Technological development of an interferometer for Multi Spectral Partially Interferograms (MSPI).

In 30 seconds

This research explores a static interferometer design for SWIR atmospheric observation, utilizing a surface-bonded hexagonal beamsplitter to eliminate moving parts. By optimizing glass plate shapes and air gaps during assembly, the design minimizes as-built uncertainties in optical path difference. This integrated approach ensures the stability required for high-precision spectral data acquisition from space.
