Abstract

The invention discloses a laser dazzler with an adjustable laser beam divergence angle. The laser dazzler comprises a laser emitting device, a concave lens, a convex lens, a transmission motor and a control circuit; the laser emitting device, the concave lens and the convex lens are placed in sequence from left to right and are positioned on the same axis; the distance position between the laser emitting device and the concave lens is fixed, and the distance between the concave lens and the convex lens is changed through the movement of the convex lens; a control circuit comprises a laser emitting module and a motor control module; the laser emitting module is connected with the laser emitting device; the motor control module is connected with the transmission motor. The control circuit ofthe laser dazzler with the adjustable laser beam divergence angle can realize the functions of adjusting pulse frequency, pulse width and emitting power by changing the duty cycle of a driving signalof the laser emitting device.

Description

technical field [0001] The invention relates to the technical field of lasers, in particular to a laser dazzler with adjustable divergence angle of laser beams. Background technique [0002] As a non-lethal weapon, laser dazzler is mainly used in anti-terrorism, anti-riot, military and other fields. The principle is that the laser beam sensitive to the human eye will cause short-term blindness and dizziness after the human eye is irradiated, so that it can quickly defeat the enemy without harming personal life. The laser beam of the laser dazzler currently on the market is difficult to adjust, and the irradiation distance is not large. Contents of the invention [0003] Aiming at the deficiencies in the above technologies, the present invention provides a laser dazzler with adjustable laser beam divergence angle, which uses the optical principle of the lens group to realize the adjustable laser beam divergence angle. [0004] In order to achieve the above object, the pre...
