Abstract

The results of the laboratory evaluation of three high resolution infrared imaging systems are presented. The systems were evaluated for their minimum resolvable temperature difference (MRTD) at spatial frequencies from 0.02 to 0.16 cycles per milliradian and at ambient temperatures in the range of -7° C to 20° C. The results of these tests are compared with the predicted dependence of the MRTD given in the ASHRAE Standard 101^-83. It is shown that the dependence on temperature of the MRTD of two of the systems is predicted well by the theory given in the ASHRAE standard. The calibration curves of the infrared imaging systems are given. These are in good agreement with those given by the manufacturers of the equipment.
