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.
