FIELD: physics.SUBSTANCE: hyperspectral sensor or imager has a laser for illuminating an object and a two-dimensional detector for detecting light emitted by the laser and transmitted through the object. The laser is a chirped laser which is designed to output multiple chirped pulses having different wavelength ranges, the multiple chirped pulses being merged to form an extended continuous spectrum for illuminating the object.EFFECT: simple design, improved sensitivity and dynamic range.26 cl, 8 dwg |
