Range finder based on erbium glass human eye safety laser device

Abstract

The invention discloses a range finder based on an erbium glass human eye safety laser, which comprises a base, a protective cover, a casing, a laser emitter and a laser receiver. There are reinforcing ribs on the side of the casing and a rectangular opening on the side of the casing. There is a rectangular cover covering the rectangular opening inside, the rectangular cover is provided with a rotating shaft, the first threaded column is fixed on the rectangular cover, the second threaded column is fixed on the outer side of the shell, and a locking block is also included. There is a through hole on the locking block, through which The diameter of the hole is equal to the outer diameter of the first threaded column, and a nut is also included. There is a threaded groove inside the nut, and a connecting rod connected to the bottom of the drone is arranged on the top of the shell. When the device is located at a high altitude, the internal air pressure is higher than the external air pressure, and the internal air pressure pushes the rectangular cover to stick to the inside of the shell, so that the electronic components inside the shell, such as the eye-safe laser, still work under the same atmospheric pressure environment as the ground. It will not cause its performance to decline, and the ranging accuracy of the airborne human eye-safe laser range finder is improved.

Description

technical field [0001] The invention relates to an eye-safe laser range finder, in particular to a range finder based on an erbium glass eye-safe laser. Background technique [0002] Laser ranging has a long history in the military. Since the invention of the first ruby ​​laser in 1960, the research on laser ranging has begun. Compared with microwave ranging, laser ranging has better directionality and higher ranging accuracy. Moreover, laser ranging has long range, strong anti-interference ability, and good concealment. These advantages make laser ranging widely used. Applications. [0003] The laser range finder is a device equipped with a laser. The early laser range finder caused damage to the eyes of the user during war and training, and even caused blindness to the user in severe cases. With the development of laser research, the safety of laser users has attracted the attention of scientists. The development of laser range finders that are safe for human eyes has b...
