Abstract
In a method for boresighting an infrared search and track sensor to an inertial reference frame provided by a boresight module, a collimated image of a reticle pattern of the boresight module is projected. The projected image is scanned with the sensor to obtain a scanned image. Rotation of the scanned image due to boresight module roll and distortion of the scanned image due to sensor roll are isolated. Distortion of the scanned image due to sensor roll is removed. An arrangement in an infrared search and track sensor is also disclosed.
