Abstract

The invention discloses an optical axis and pupil calibration composite optical system for light beam tracking and pointing equipment. The optical axis and pupil calibration composite optical system comprises a common-aperture beam shrinking system, a first spectroscope, an optical axis detection imaging system and a pupil detection imaging system, the common-aperture beam shrinking system is respectively in light path connection with the optical axis detection imaging system and the pupil detection imaging system through a first spectroscope; according to the invention, the deviation of the main laser, the optical visual axis and the mechanical axis of the photoelectric turntable can be corrected, the target tracking precision and aiming precision of the system are ensured, the cost of the system is saved, and the space of the system is reasonably utilized.

Description

technical field [0001] The invention relates to the technical field of photoelectric tracking and aiming imaging, and more specifically, relates to an optical axis pupil calibration compound optical system for beam tracking and aiming equipment. Background technique [0002] Beam control and tracking and aiming equipment (ATP for short) is an important part of laser directed energy weapons. Its purpose is to transfer high-energy laser to the transmitting telescope through the photoelectric tracking and aiming platform, focus the laser on the far-field target, and achieve strike and attack on the target. destroy. The main function is to complete the functions of target tracking and detection, optical axis calibration of the inner optical path, and high-precision aiming. [0003] The current existing technology has the following disadvantages: due to the deviation of the main laser, the optical axis of sight, and the mechanical axis of the photoelectric turntable, the trackin...
