FIELD: optoelectronic instrument making.
SUBSTANCE: invention relates to optoelectronic instrumentation and relates to a method for deselecting element sequences, maximally reducing signal-to-noise ratio of channels of infrared photosensitive module with mode of time delay and accumulation. Method includes irradiation of photosensitive module by means of absolutely black body, measurement of voltages of signals and noise of elementary sequences of channels of photosensitive module, calculation of average arithmetic values of voltages of signals and dispersions of voltages of noise of elementary sequences of channels, detection of elementary sequences of channels to be disconnected, and disconnection of detected photosensitive module channel chains. Detection of element sequences of channels to be disconnected is carried out by processing the calculated arithmetic mean values of signal voltages and variances of noise voltages of element sequences of channels of the photosensitive module using the criterion for detecting element sequences which maximally reduce the signal-to-noise ratio.
EFFECT: high sensitivity of photosensitive modules.
