Description
Technical field
The present invention relates to the dustproof window component and its method of work of a kind of laser night-vision device, belong to laser infrared night observation device
Technical field, is related to visible ray, near-infrared optical and Display Technique.
Background technology
With the fast development of social economy, people also progressively strengthen the consciousness of safety precaution, and the requirement to security device is got over
Come higher, laser night-vision device has huge excellent compared to common thermal camera in terms of nighttime imaging definition, monitoring distance
Gesture, is increasingly paid attention to by user.
Because laser night-vision device is typically all installed in the wild, environmental condition is extremely severe, and laser night-vision device window glass can be by
Dust, raindrop attachment is so as to influence the image quality of night vision device, and laser night-vision device laser lighting window adheres to if there is dust,
Laser output power can be influenceed, causes laser light filling not enough, or even dust has scattering process to laser, produces veiling glare, seriously
The imaging definition of video camera is influenceed, therefore laser night-vision device window glass must carry out specially treated, reach anti-reflection dust-proof
Effect.
Chinese patent Authorization Notice No. is a kind of CN203327134U patent document " ball-type laser night-vision device with rain brush "
There is provided a kind of ball-type laser night-vision device with rain brush is disclosed, it can make rain brush is complete, stablize cleaning imaging window to protect glass
