Abstract

The invention relates to a beam-target coupling sensor belonging to the field of photoelectric sensors, which overcomes the problems with conventional monitoring systems including high difficulties indesign, manufacture, and assembling, high cost, high liability to undesired phenomena such as distortion and scattering, as well as low ensurance for targeting accuracy and reliability concerning special targets. The sensor includes three monitoring elements including an upper one, an intermediate one, and a lower one, each including a CCD, a micro object lens, a laser reflector, and an annular LED light source for monitoring the spatial position and posture of a target. The annular LED is used for illuminating the target. An incident laser beam on a target point is reflected onto the image surface of the CCD via the laser reflector. A vacuum motor and a ball screw transmission pair are used to realize focusing of the upper and lower micro monitoring systems, and an electric micro displacement platform is used to realize focusing of the intermediate micro monitoring system. In addition to accurate and fast guiding, the invention realizes zero impact of the target on light beam guidingbecause of indirect cast of laser light thereon, thus achieves improved adaptability to different targets.

Description

technical field [0001] The invention relates to the field of photoelectric sensors. Background technique [0002] The laser inertial confinement fusion experiment is one of the most cutting-edge research topics in the world at present. The experiment realizes the fusion reaction by bombarding the deuterium-tritium target with multiple high-energy lasers, thereby realizing controllable fusion. In the laser inertial confinement fusion experiment, it is necessary to guide multiple laser beams to the specified position on the experimental target. In the past, the laser guidance method is to directly hit the laser on the target and monitor the position of the light spot on the target through the monitor. Since the wavelength of the target laser is usually ultraviolet light, and the light detected by the monitoring system is in the visible light band, the distance between the target and the light spot To monitor the chromatic aberration, the solution to the chromatic aberration p...
