With Color Sequential Illumination Patents (Class 348/269)
  • Patent number: 5379065
    Abstract: A hyperspectral imager includes a focal plane having an array of spaced image recording pixels receiving light from a scene moving relative to the focal plane in a longitudinal direction, the recording pixels being transportable at a controllable rate in the focal plane in the longitudinal direction, an electronic shutter for adjusting an exposure time of the focal plane, whereby recording pixels in an active area of the focal plane are removed therefrom and stored upon expiration of the exposure time, an electronic spectral filter for selecting a spectral band of light received by the focal plane from the scene during each exposure time and an electronic controller connected to the focal plane, to the electronic shutter and to the electronic spectral filter for controlling (a) the controllable rate at which the recording is transported in the longitudinal direction, (b) the exposure time and (c) the spectral band so as to record a selected portion of the scene through M spectral bands with a respective expos
