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. In calculation of this term only monochromatic radiation of sources in previous studies. As we are going to use dispersion method for air refraction influence attenuation, light sources of different wavelengths must be used. Because of dispersion in lenses of the objective the distribution of energetic sensitivity along the distance is different for wavelengths used, and the response of the receiver depends on the wavelength, too. Thus the term of energetic sensitivity is revised for a spectrum and spectral response of the sensor is taken into account. The suggestion of using of effective energetic sensitivity in preliminary assessment of system sensitivity is confirmed by experimental results.
