HISUI is the hyperspectral imager observes the wavelength range from VNIR to SWIR with 185 bands.
Specification
The main specifications of HISUI is shown in the table on the right. HISUI continuously acquires 185 band imaging from VNIR to SWIR range. The most remarkable feature is the high spectral resolution. It allows contiguous measurement of reflectance spectrum, which show characteristics of the target materials.
HISUI has both performances, an observation width that can cover almost all areas for resource exploration in a mission period, and a spatial resolution appropriate for resource exploration.
