Paper Abstract

Onboard real time analysis of remotely sensed images can reduce the data flow to the ground stations for high resolution Earth monitoring systems. Fast image texture analysis is possible by processing of optically obtained Fourier spectrum of the image. In the paper the questions of incoherent light source usage in the optoelectronic Fourier spectrum analyzer are considered. Using of incoherent light source of specific size makes it possible to provide an optimal spatial filtering of the spectrum, reduce a sensitivity to phase distortions and obtain a compact and rugged design of the device, suitable for onboard installation. Special algorithm of spectrum image digitizing is developed to enlarge a range of spatial frequencies to be processed and maximize the photosensitivity. The algorithms for texture properties recognition are developed and tested using prototype incoherent Fourier spectrum analyzer. Prototype description is also given.
