Paper Abstract

The results obtained in the development of a laboratory prototype of intelligent spectrometric system with real time digital signal processing are shown in this paper. The system is acombination of visible range spectrophotometer and focussing holographic grid with photodiode linear structure, i.e.the sensor, real time digital signal processing controller and display processor for gray level visualization, together with PC/XT controlLing computer. The twodimesional adaptive differential pulse code modulator with simultaneous correction of sensor dark current introduced into the real time controller allows the registration of measurments with resolution of 10 bit/el and real time data compression 2.5 times. During computation of colorimetric estimations or wideband photo-metric compression the possibilities for express analysis increase together with the enhancement of the signal-to-noise ratio. The system control and the visualization of spectral and colorimetric features in the data flux is made with personal computer together with display processor with resolution 512x512x8 and interactive software. It may be used for ground-based and onboard complexes.
