Abstract: A system for active co-boresight measurement includes a detector, first and second steering mirrors, and a controller. The detector detects a portion of a transmission beam emitted by a transmitter and a portion of a received beam received from a remote terminal. The controller instructs the first steering mirror to scan the detected portion of the received beam to determine an alignment position. The controller controls a position of the first steering mirror to align the portion of the received beam with the alignment position on the detector, and controls a position of the second steering mirror to align the detected portion of the transmission beam with a defined position on the detector. The detected portion of the received beam at the alignment position and the detected portion of the transmission beam at the defined position correspond to the received beam and the transmission beam being aligned. A system for active co-boresight measurement includes a detector, first and second steering mirrors, and a controller. The detector detects a portion of a transmission beam emitted by a transmitter and a portion of a received beam received from a remote terminal. The controller ...more ...less

Abstract: Parallel laser light beams (L11, L21) are irradiated from different positions into a telescope (200). Beams of laser light (L12, L22) are incident on a secondary mirror attitude detection mirror (127) from different locations. Laser light detectors (128, 129) detect each beam of laser light reflected by the secondary mirror attitude detection mirror (127). A first attitude calculator (130) determines an amount of attitude variation of a secondary mirror (230) based on a result detected by the laser light detectors (128, 129). The laser light detectors (134, 135) detect each beam of the laser light reflected by the primary mirror (220) and the secondary mirror (230) after entering the telescope (200). A second attitude calculator (136) determines an amount of attitude variation of the primary mirror (220) based on a result detected by the laser light detectors (134, 135) and the result detected by the laser light detectors (128, 129).
