Embodiment Construction

[0031] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0032] Such as figure 1 As shown, a continuous focusing high-energy laser emission tracking and aiming system includes a lower shelter 91, an azimuth axis 92, and an upper pitching body 93, and the azimuth axis 92 is rotatably connected to the top of the lower shelter 91 and the top of the upper pitching body 93. bottom, so that the upper pitching body 93 can rotate n×360° horizontally.

[0033] The lower shelter 91 is equipped with a laser 1 , a calibration fast mirror 2 , a beam splitter 3 , a primary beam expander system 4 , a fine tracking imaging subsystem 7 , and an optical axis calibration reflection element 8 . The laser 1 emits high-energy laser upward, and after being reflected by the collimated fast mirr...

Abstract

The invention relates to a continuous focusing high-energy laser emission tracking aiming system which comprises a laser, a beam splitter, a primary beam expanding system, a secondary beam expanding system and a fine tracking imaging subsystem. After being reflected by the beam splitter, laser emitted by the laser device is focused to a target after being expanded by the two stages of beam expanding systems in sequence. Light reflected by a target sequentially passes through the two stages of beam expanding systems to return, penetrates through the beam splitter and is focused and imaged by the fine tracking imaging subsystem. The primary beam expanding system comprises a transmission type system consisting of a focusing eyepiece and a fixed eyepiece; and the secondary beam expanding system comprises a reflective system consisting of a convex reflecting mirror and a concave reflecting mirror. According to the invention, two-stage beam expanding is adopted, so that the focusing beam is prevented from deviating from the central optical axis caused by focusing of a secondary mirror of a traditional off-axis reflection type beam expanding system; the fine tracking imaging subsystem and the two-stage beam expanding system are completely designed in a common aperture mode, and deviation of a laser emission axis and an aiming axis caused by the imbalance phenomenon of an optical system in the laser focusing adjustment process is avoided.

Description

technical field [0001] The invention relates to the field of laser beam control, in particular to a continuous focusing high-energy laser emission tracking and aiming system. Background technique [0002] Due to the advantages of high energy density, good directionality, good monochromaticity, and fast transmission speed, high-energy lasers are widely used in military and civilian fields. In recent years, the rapid development of high-energy lasers has further expanded the application of lasers, and has a wide range of applications in manufacturing, healthcare, smart grids, and military investigations. The high-energy laser emission and tracking and aiming system is one of the typical applications. Its main working principle uses its own laser equipment to expand the high-energy beam, and control the directional transmission through the beam emission to focus on the target, so that it is disturbed, suppressed, and at the same time The fine tracking and aiming system can per...
