Portable Multispectral Telescope

A telescope produces multiple video outputs representing coregistered images in multiple spectral bands that can range from ultraviolet through far infrared. Although the overall function of the telescope is partly equivalent to that of a color television camera equipped with telescopic lenses, its basic optical configuration differs from that of a color television camera, and it is designed for different applications. In the original intended application, the telescope will be used in research on remote optical detection of stress in plants. By suitable choice and placement of optical components, as described below, the telescope can readily be configured for other special applications.
