More Information
  • Aiming at the space laser communication system requirement of miniaturization, this paper proposes a scheme of using the four-quadrant detector to complete the acquisition and tracking. By analyzing the position distribution of the spots on the four-quadrant detector (4QD), the acquisition models are derived for the three kinds of spots distribution. Through the calculation of the position of the spots and the accurate calibration of the tracking mechanism, the high precision tracking is realized. Then besed on the laserteco and system test platform the capture and tracking scheme and detection performance of the 4QD are experimentally verified. The test results show that under the laboratory dynamic conditions, using 4QD as the capture and tracking detector, the capture probability is up to 100%, and tracking accuracy is better than 3μrad, which verifies the feasibility of the scheme and lays a foundation for the miniaturization design of the laser terminal.

  • Overview: Before establishing the communication link, acquisition, pointing and tracking (APT) is needed to complete in the space laser communication system. Charge coupled device (CCD) or four-quadrant detector (4QD) are usually selected as capture and tracking detectors to determine the spot center, and miss distance is sent to the servo system to complete the capture and tracking tasks. At present, most laser communication systems choose 800 nm and 1550 nm. Compared with the 800 nm, 1550 nm laser has the advantages of having little impact on human safety and atmospheric environment. However, CCD detector has low response sensitivity and cannot meet the requirements for the 1550 nm, so 4QD is the ideal choice. In recent years, there have been many researches on 4QD in the field of laser communication. For 4QD applications mostly limited to the desktop system, not to dynamic test, 4QD is applied to capture and tracking studies did not report. Using 4QD as capture and tracking detector, laser communication system does not need to be high power beacon laser, the beacon transmitting branch and beacon capture detector. It can reduce the complexity of the system, power and volume.

    Aiming at the space laser communication system requirement of miniaturization, this paper proposes a scheme of using the four-quadrant detector to complete the acquisition and tracking. By analyzing the position distribution of the spots on the 4QD, the acquisition models are derived for the three kinds of spots distribution. Through the calculation of the position of the spots and the accurate calibration of the tracking mechanism, the high precision tracking is realized. Then besed on the laserteco and system test platform the capture and tracking scheme and detection performance of the 4QD are experimentally verified. The laser terminal used in the experiment is a laser terminal with a tracking detector of 4QD, which can receive 1550 nm and 1 M intensity modulation signal light. The detector's field of view is 2 mrad, the coarse pointing mechanism is a latent looking structure, and the pointing accuracy is better than 30 μrad. The fine tracking mechanism is a two-dimensional deflection mechanism of piezoelectric ceramics. Its deflection range is 4mrad and positioning accuracy is better than 3 μrad. The test results show that under the laboratory dynamic conditions, using 4QD as the capture and tracking detector, the capture probability is up to 100%, and tracking accuracy is better than 3 μrad, which verifies the feasibility of the scheme and lays a foundation for the miniaturization design of the laser terminal.
