ABSTRACT:
A system for compensating for heating effects in a mirror. Different areas of the mirror are associated with buried temperature sensors. Each temperature sensor is monitored, and used to create a map of current temperatures. The map of current temperatures may be corrected according to baseline values, and then is used to compensate for temperature differences.
