Abstract

An off-axis laser beam directional transmitter, comprising: a light source, a first off-axis aspheric reflector, a second off-axis aspheric reflector, a first fast control reflector, a second fast control reflector, a driver, a control The incident beam emitted by the light source that is not transmitted along the main optical axis is transmitted along the off-axis direction, reflected by the first off-axis aspheric reflector, and then transmitted to the first fast control reflector, and reflected by the first fast control reflector transmitted to the second off-axis aspheric mirror, and finally used for the final launch through the second fast control mirror; The moving sensor obtains the relevant position, velocity and acceleration information, and sends it to the central processing unit, so as to control the driver to control the precise movement of the mirror to achieve precise control of the azimuth, elevation and focal length of the outgoing beam, and then directional launch the laser to destroy the target.

Description

technical field [0001] The invention belongs to the technical field of laser beam emission control, and in particular relates to a laser beam off-axis directional emission device with a fast control reflector and an off-axis aspheric reflector as core components. Background technique [0002] With the rapid development of lasers, especially the maturity of fiber lasers, it is possible to develop laser weapons, especially fiber laser weapons. The emission control of the corresponding beam director has become one of the core technologies of laser weapons. [0003] For conventional laser weapons (such as chemical laser weapons), the beam director often adopts a coaxial emission system (such as the Cassegrain system), such as figure 1 shown. Since the internal transmission of the system is a hollow beam, the secondary mirror in the coaxial emission system will not block the transmission of the beam, so the beam can be directed and emitted with high efficiency. However, for fi...
