Laser dazzling optical system

Abstract

The invention discloses a laser dazzling optical system, which is characterized by comprising a laser source, a collimating lens group, a dodging sheet, a first-stage variable-magnification beam expanding system and a second-stage fixed-magnification beam expanding system. The laser source is used for emitting laser; the collimating lens group collimates the laser emitted by the laser source into parallel light beams; the dodging sheet is used for converting the parallel light beams into uniform parallel light beams; the first-stage variable-magnification beam expanding system is used for expanding the uniform parallel light beams, so that the aperture of the emergent parallel light beams is increased and adjustable; and the second-stage fixed-magnification beam expanding system is used for increasing the aperture of the light beams emitted in parallel again so as to realize a laser dazzling effect. According to the laser dazzling optical system provided by the invention, the action distance and the action area of the light beams are increased, the light beam intensity is more uniform and stable, and no damage is caused to human eyes.

Description

technical field [0001] The invention relates to an optical application field, in particular to a laser glare optical system. Background technique [0002] Currently installed laser blinding weapons generally have shortcomings such as short action distance, small spot area, easy to cause permanent damage to the eyes, or insufficient effect. The core of laser dazzle weapons is the glare optics system. The current glare optics system has problems such as short action distance, small action area, and large changes in energy density with the switching of working modes. Therefore, how to solve the above technical problems is the direction that those skilled in the art need to work on. Contents of the invention [0003] The object of the present invention is to provide a laser glare optical system. By using the system, a dazzling light beam with long working distance, large and constant active area and uniform intensity can be realized, and damage to human eyes can be prevented....
