摘要：

Application of spectral devices for the detection of small concentrations of substances presents high demands on the signal dynamic range. Commonly used multielement photodetectors have a substantial nonuniformity of both sensitivity and dark signal that significantly narrows the dynamic range. For correction of such situation it was designed an amplifier with individual correction of gain and offset of a dark signal for each pixel that considerably enhances dynamic range and presents an ability to effectively detect weak signals.
