Abstract
Energetic sensitivity of a system with optical equisignal zone is considered in the paper. Energetic sensitivity is a criterion for choosing components of such a system and determines its potential accuracy. The term of energetic sensitivity is revised for a spectrum and spectral response of the sensor is taken into account. New method of evaluating of the position of optical equisignal zone is proposed. The method is based on evaluation of the position on the CMOS array. Digital method of signal processing is compared to analog one. Digital method has some advantages over analog in functionality but still yield to analog in speed.
