Abstract

The invention provides a compact self-adaptive laser defense system, including: a primary mirror, a deformation focusing secondary mirror, a tilting mirror, a beam splitter, a Hartmann sensor, a laser collimating optical system, a laser, an illumination system and a control device. The anamorphic focusing secondary mirror in the system mainly has the function of correcting high-order aberrations and defocusing in a large range; the Hartmann sensor is used to detect wavefront distortion, and the measurement results are used for tilt closed-loop and defocusing high-order aberration correction. The invention uses a Hartmann sensor instead of a tilt tracking sensor to detect wavefront aberration, and corrects it with a deformed focusing secondary mirror, effectively eliminating the influence of atmospheric turbulence on the shape of the spot, increasing the power density of the spot, and improving the active defense capability. Compared with the existing self-adaptive laser defense system, the present invention combines the focusing secondary mirror with the deformable mirror, so that the structure of the optical system is more compact, the reflection surface is less and the energy loss is smaller.

Description

technical field [0001] The invention relates to the technical field of light beam control in optical instruments, in particular to a compact self-adaptive laser defense system. Background technique [0002] UAV is an unmanned aircraft controlled by radio remote control equipment and self-contained program control device. In the 1990s, Western countries fully realized the role of drones in warfare, and adopted various new technologies to vigorously develop drones. Today, UAVs already have multiple functions such as reconnaissance, bombing, and interference. With the continuous emergence of military and civilian drones, anti-drone awareness has been continuously improved due to the needs of national security and homeland security, and countries have already carried out research work in this area. . However, using traditional means to fight against UAVs not only has a low success rate, but also may cause collateral damage to the ground and the crowd, and laser defense is one...
