The Boresight Alignment Module (BAM) is used to co-align multiple imaging systems to each other and to laser transmitters. The BAM consists of a silicon or InGaAs camera rigidly held and combined optically with the target wheel. Through autocollimation, the line of sight of the collimator is transferred to the camera, creating a boresight reference. The laser camera captures laser energy from the UUT laser transmitter. The image of the laser spot is digitized with 12 bit accuracy, a centroiding function is performed by the IRWindows™5 software, and the measured off-set from boresight is reported. Boresighting is the primary test performed with this module, but the BAM is also capable of other beam-profile related tests, including divergence measurement.
