Recalculation of spectral sensitivity of photodetector arrays with a relatively low signal-to-noise ratio necessitates the analysis of noise filtering with maintaining of the positions of boundaries and maximum sensitivity. Methods for filtering of spectral characteristics of sensitivity (moving average method and its modifications, spline interpolation, calculations using the Bezier curves, and Savitzky–Golay procedure) are compared. Criteria for selection of nondestructive calculation procedure that does not introduce errors in the boundaries of the range and maximum sensitivity of photodetector arrays are determined. An optimal method for recalculation of spectral sensitivities of photodetector arrays is chosen and substantiated.
