Method and apparatus for compensating a radiation sensor for ambient temperature variations

摘要

Methods and apparatus for compensating a radiation sensor for ambient temperature variations. Ambient temperature variations may produce undesirable artifacts in electronic signals output by a radiation sensor. In some cases, such artifacts may detrimentally reduce the dynamic range of the sensor and/or processing circuitry associated with the sensor with respect to radiation of interest. The radiation sensor may be compensated for such undesirable artifacts by, for example, adding an appropriate offset to a sensor bias voltage or a sensor bias current, and/or controlling a temperature of the radiation sensor, based on variations in the ambient temperature.
