Abstract: Systems and methods relating to a multi-slit hyperspectral imager. The imager is configured with multiple slits that are parallel to one another. Each slit produces its own hyperspectral cube and is limited to a specific wavelength range. The multiple slits produce multiple data sets, obtained in quick succession, for the same section of an area to be imaged. In optical spectrometry applications such as trace gas sensing and quantification, this allows for improved measurement precision. The imager may be used for any gas of interest by adjusting the wavelength range to one that contains absorption features of the targeted gas.
