A system for aligning components of an imaging device includes an imaging device, and a test camera. The imaging device includes a lens and a focal plane array (FPA). The FPA defines an optical axis and includes at least two test elements configured and adapted to emit a light through the lens. The test camera is configured and adapted to be mounted to and pre-aligned with the lens of the imaging device to receive a light from the at least two test elements.

Systems and methods for aligning imaging devices

A method of controlling FPA system stabilization includes calculating FPA adjustments as a function of FPA temperature and adjusting a TEC set point to assist the FPA adjustments in attaining a predetermined level of FPA performance. Adjusting the TEC set point can include adjusting the TEC set point as a function of at least one of ambient temperature, FPA temperature, or disparity between the predetermined level of FPA performance and a level of FPA performance obtainable by calculating the FPA adjustments as a function of FPA temperature alone without adjusting the TEC set point.

Thermoelectric cooling management

A system for determining lens position including a first capacitor plate disposed on a stationary housing of a camera. A second capacitor plate is disposed on a rotating lens component of the camera. A processor is operatively connected to the first and second capacitor plates to identify the position of the lens of the camera based on capacitance between the first and second capacitor plates.
