Multispectral pushbroom array imager
Abstract
The sensitivity of multispectral sensing depends on the optimization of wavelengths, bandwidths, and number of bands. A method is described allowing for remote control of spectral band selection and therefore for real time in-orbit optimization depending on the mission or environmental conditions. A two-dimensional solid state detector senses a spatial dimension in one coordinate; the other coordinate records spectral information. The pushbroom scan creates the remaining spatial coordinate by timed exposures. Programming of the sensor readout allows for flexibility in spectral band selection.
