Abstract
The present invention is directed to a method for improving measurement accuracy of infrared imaging radiometers utilizing a small pitch infrared detector array. The detector offset is changed so that the detector output, when observing a particular object temperature, is maintained at a desired level over a range of ambient temperatures.
Claims6
A method for improving the measurement accuracy of infrared imaging radiometers, comprising the steps of:
- receiving an observed image in an infrared detector array;
- estimating the convolution of the true image;
- and
- radiometrically deconvolving said true image utilizing a modulation transfer function.
1 more element
A method for improving the measurement performance and dynamic range of infrared imaging radiometers including the steps of:
- initially producing a detector offset value;
- changing said detector offset value based upon the temperature of said detector subsystem.
