Non-imaging glimmering night-vision enhancing lens

Abstract

The invention discloses a non-imaging glimmering night-vision enhancing lens, which comprises a gain lens, wherein electrode films are arranged on upper and lower surfaces of the gain lens. A transparent matter permeates into or is wrapped by a laser working matter to form the gain lens. When the non-imaging glimmering night-vision enhancing lens is used, the electrode films on the upper and lower surfaces of the gain lens are connected to a pumping power supply of a pumping system. The laser working matter in the gain lens is subject to dark discharge pumping under the action of current which passes through the space between the electrode films on the upper and lower surfaces of the gain lens, so that the electron transition pumped to a high energy level is stimulated to realize stimulated radiation when light at a specific waveband passes through the gain lens, thus a glimmering night-vision effect is achieved. A glimmering night-vision instrument equipped with the non-imaging glimmering night-vision enhancing lens has the advantages of small volume and light weight, is convenient for wearing and can hardly cause visual fatigue.

Description

technical field [0001] The invention relates to an optical instrument, in particular to a non-imaging low-light night vision enhancing lens for a low-light night vision device. Background technique [0002] The low-light night vision device is a kind of instrument that can use the low-brightness night sky light, star moonlight, atmospheric glow and other natural light reflected by night targets to enhance and magnify it to hundreds of thousands of times so as to be suitable for night observation with the naked eye. [0003] At present, the existing low-light night vision devices at home and abroad are made according to the physical principle of the photoelectric effect. After photons enter the night vision device, they hit the metal plate to generate photoelectrons. These electrons pass through a thin disk placed in front of the light screen. There are millions of microchannels (ie, millions of pixels) on the disk. After entering the microchannels, electrons are multiplied a...

Problems solved by technology

Low-light night vision devices with this structure generally require complex lens systems, focusing systems and imaging space, so the overall structure is large and not suitable for wearing, and the imaging of low-light night vision devices with this structure is far from the use The eyes of the patient are relatively close, so it is very easy to cause visual fatigue
