Abstract

In infrared imager system of using infrared focal sensor, for the responsivity heterogeneity among focal plan image elements and sensors and amplifiers can not be made in model of one to one, this kind of system asks for compensation of the heterogeneity of sensor response. Measuring the heterogeneity of focal plane image elements response accurately is the key to assure the quality of compensation. The article introduces a new method of measuring the heterogeneity of focal plane image elements response. It avoids the affect of black body radiate plane's spatial heterogeneity on the measuring result and gets higher measuring precision.
