A method of analyzing Imaging Sensors independent of type of sensor, electro-optic EO, photographic, infrared etc. involving the concepts of Signal-to-Noise Ratio, Modulation Contrast, Resolution, Target Response Function as related to Modulation Transfer, Function MTF and other system and operational parameters, is presented. Equations are derived for predicting resolution as a function of object-background modulation contrast, exposure or irradiance, and wavelength, from Detector-Display Characteristic Curve, Optical Transfer Function or Spread Function, RMS Noise Characteristics, Path Radiance, Veiling Glare, etc. Detection and Resolution Range equations are also derived. It is recommended that the approach outlined in this report be taken when comparing sensor systems of different types.
