摘要	A medium-wave-infrared (MWIR) and single-photon-laser common-aperture optical system was developed to realize target detection, tracking, and ranging of long-distance civilian aviation aircraft. In this study, the working principle of the laser/infrared common-aperture system was presented, and the target radiation characteristics, system operating range, and size of the aperture were analyzed. An R-C optical system with a dichroic lens as a secondary mirror was used to realize the dichroic design of the common-aperture system. A small aperture was set in the path of the single-photon laser, and the stray light suppression of the aperture was verified by modeling and simulation. High-precision assembly and line-of-sight calibration revealed that the laser/MWIR common-aperture optical system exhibited high-quality imaging. The modulation transfer function of the laser/MWIR optical system was measured to be 0.28(@20lp/mm. The prototype was used to detect and track a civilian aviation aircraft, and the results of the experiment revealed that the range of the common-aperture system exceeded 225 km. The proposed device can satisfy the application requirements for early warning and ranging of long-distance targets in aviation, aerospace, and ground detection. 2021 Science Press.
