Abstract

This paper firstly discussed respectively the transform mechanism of photons-to-electron of photoconductive and photovoltaic infrared detector cells from the point of the micro-mechanism, then makes the macro-analysis about the equation relation between the irradiation area and the output signal of infrared detector cells under the condition of uniform irradiation. According to the result, this text consolidates the relation between the input irradiation area and the output voltage of photovoltaic and photoconductive infrared detector cells. In the middle part, this paper illustrates the physics meaning of the modulation transfer function of photovoltaic and photoconductive infrared detector cells which produced by the scanning movement of the cell. This text puts forward the method of measuring the MTF of infrared detector cells. This text names it the knife-edge scanning method. Last part, the text calculates the MTF of infrared detector cells in the ideal condition that detector cells in the ideal condition that detector cells are homogeneous and the geometry of cells is the regular rectangle. At last the paper sums up the factors, which affect the MTF of photovoltaic and photoconductive infrared detector cells.
