METHOD FOR FORMING IMAGE SIGNAL USING CHARGE-COUPLED MATRIX DEVICES Russian patent published in 2022 - IPC G01R23/16 

FIELD: measuring technology.

SUBSTANCE: invention relates to measuring technology, namely to the field of spectroscopy, and can be used to analyze the data of the received spectrum of optical signals from a charge-coupled device. The method for generating an image signal using charge-coupled matrix devices consists in projecting an image onto a photosensitive surface of a charge-coupled device, accumulating charge packets, and calculating a discretely specified signal accumulation time t_j in the range from t₀ to the maximum allowable signal accumulation time t_N and measuring the amplitude of the spectrum components of the received wideband image signal for all values ​​of t_j, on the basis of which the coefficient of the linear dependence of the increase in the amplitude of the output current of the spectrum point in the i-th optical element of the matrix device with a charge-coupling from the signal accumulation time K_i is calculated and the coefficients of the linear dependence of the angular coefficient of increase in the output current amplitude of a point of the spectrum with increasing signal accumulation time α and β to recalculate and correct the amplitude of the output current at each point of the spectrum of the projected image.

EFFECT: improving the accuracy of correction of non-linear distortions of the spectrum obtained on the spectrum analyzer.
