Optical spectrum sensor being switchable between hayperspectral and multispectral observation

A multi-band/hyper spectrum sensor having a sight field in a longitudinal direction in the direction (i.e., CT direction) normal to the direction of flying of an artificial satellite, converts a slit image incident via a differential grating 4 on a detector 5 to a two-dimensional image having the sp...

Summary:A multi-band/hyper spectrum sensor having a sight field in a longitudinal direction in the direction (i.e., CT direction) normal to the direction of flying of an artificial satellite, converts a slit image incident via a differential grating 4 on a detector 5 to a two-dimensional image having the spreading of a slit shape (i.e., (b) CT direction) and the spreading in the wavelength dispersing direction (i.e., (a) direction normal to the CT direction). To receive the two-dimensional image, a two-dimensional CCD is used as the multi-band/hyper spectrum detector 5. Light intensity data focused on the two-dimensional CCD is binning read out according to a command from the earth surface, thus taking out spatial and wavelength resolutions while changing the same.
