Embodiment 1

[0030] After the energy-amplified high-power laser beam is grouped and transmitted over a long distance, it is focused by the shooting lens to the impact point of the physical target. Since the silk target is only tens of microns, it will not block the laser beam. Therefore, the laser beam will continue to Backward transmission, at this time, the laser beam carries the frequency domain information introduced by the silk target (that is, the shielding of the silk target results in the loss of part of the energy share in the frequency domain). A lens is placed at the near-field position of the beam behind the silk target to collimate the laser beam into parallel light. The image sensor is used to receive the intensity information of the near-field of the beam, and the near-field deconvolution analysis of the beam is performed to obtain the laser beam and the silk target through inversion. mutual position information, and then complete the beam guidance.

Abstract

The invention relates to a laser beam guiding method for aiming at a silk target, which belongs to the technical field of laser beam control. The spectral distribution of the incident light field of the laser beam is set so that the laser beam is focused to the impact point of the physical target and then incident on the silk target to continue transmission. The spectral distribution of the near-field of the laser beam behind the silk target is deconvolution analysis and processing of the frequency domain of the near-field of the laser beam and its inverse conjugate frequency domain, and the inversion obtains the mutual position information of the laser beam and the silk target, and then completes the beam guidance. , the present invention utilizes the spatial high-frequency component of the laser beam to convolve with the silk target, carries the relative position information of the silk target and the laser beam focal spot, and analyzes the near field of the laser beam after passing through the silk target in the frequency domain to obtain the laser beam and the laser beam The mutual position information of the silk target, and then complete the beam guidance of the silk target, can realize the precise guidance of the most probable energy center of the beam incident on the silk target, and the closed-loop control ensures the guidance accuracy to the greatest extent, without the introduction of special auxiliary equipment, economical and practical.

Description

technical field [0001] The invention belongs to the technical field of laser beam control, and in particular relates to a laser beam guiding method for wire target aiming. Background technique [0002] Large-scale high-power lasers are a type of complex optical system, which covers multiple disciplines such as optics, mechanics, electricity, control, measurement, and installation. Its function is to create an extreme material environment and provide research on various physical processes. Targeting accuracy is a key performance indicator of large-scale high-power lasers, which is related to the success or failure of physical experiments. In order to ensure the accuracy of shooting, before each official launch, it is necessary to carry out optical path alignment and beam guidance, so that the far-field focus of all beams can be accurately converged to the impact point of the physical target. The aiming of the physical target is assisted by a target aiming and positioning sen...
