Abstract
A multispectral imaging and analysis system incorporating the use of charge coupled devices or linear arrays of detectors and which is designed to permit on-board analysis of data in real time is disclosed. An imaging system including several arrays of charge coupled devices or linear detector arrays are used to obtain simultaneously spectral reflectance data of different wavelengths for a target area. A plurality of filters each accommodating a particular bandwidth are individually associated with each array. Data from the arrays are read out in parallel and applied to a computer or micro-processor for processing. The micro-processor serves to analyze the data in real time and as may be possible in accordance with hard-wired algorithms. The data are then displayed as an image on an appropriate display unit and also recorded for further use. The display system may be operationally connected to receive a terrain image such that the target area and the analyzed spectral reflectance data are superimposed and simultaneously displayed.
