Abstract: A multispectral imager includes processing circuitry, an illumination assembly, a detector assembly, and a focusing assembly. The illumination assembly includes an array of illumination elements controlled by the processing circuitry to illuminate a scene. The detector assembly includes a detector array controlled by the processing circuitry to capture images from the scene at different wavelengths. The focusing assembly includes a lens and is controlled by the processing circuitry to adjust a focal point for the detector array. The processing circuitry generates and processes the images from the scene, taken at different wavelengths and focal points, combines the images to form a multispectral image cube for the scene, and determines a composition of an object within the scene based on a spectral profile of the multispectral image cube.

Abstract: A range determiner assembly may include an image sensor, a detector board and processing circuitry. The image sensor may be configured to obtain image data for each of three views of a target at each of a plurality of different locations along the track of a craft moving at a determinable altitude above a surface of the earth. The detector board may include a first line array, a second line array and a third line array. Each of the first, second and third line arrays may receive a respective sequence of images from a corresponding one of the three views. The processing circuitry may be configured to determine a relative distance between the craft and the target based on the image data.
