ABSTRACT:
Disclosed herein is a method and apparatus for compensating for temperature-induced scan line drift in a photoelectric imaging apparatus. A scan line drift compensation mechanism may be placed in contact with at least one of the optical components, e.g, a mirror, contained within the optical system of a photoelectric imaging apparatus. The scan line drift compensation mechanism may be formed from two members, each having a different coefficient of thermal expansion. In this manner, the scan line drift compensation mechanism is able to exert a force on the optical component in response to a change in temperature.
