Refrigeration type medium wave infrared light and laser double-mode common-caliber camera lens

Abstract

The invention relates to a refrigeration type medium wave infrared light and laser double-mode common-caliber camera lens. An optical system of the camera lens comprises a front infrared light and laser common-caliber set A, a rear infrared light set B and a rear laser set C. A positive lens A-1, a negative lens A-2, a positive lens A-3 and a light splitter A-4 are sequentially arranged on the front infrared light and laser common-caliber set A in the light incident direction. After light passes through the front infrared light and laser common-caliber set A, one path of the light is reflected to the rear infrared light set B, and the other path of the light is transmitted to the rear laser set C. A positive lens B-1, a negative lens B-2 and a reflector B-3 are sequentially arranged on the rear infrared light set B in the light incident direction. A positive lens C-1, a positive lens C-2, a reflector C-3, a positive lens C-4, a positive lens C-5, a light filter C-6 and a positive lens C-7 are sequentially arranged on the rear laser set C in the light incident direction. The camera lens has the advantages that medium wave infrared light and lasers are received in a common-caliber mode, and imaging quality, resolution, anti-jamming capability, operational flexibility and operational effectiveness are high.

Description

technical field [0001] The invention relates to a cooling-type mid-wave infrared and laser dual-mode common-aperture lens for live tracking and measurement, which belongs to the lens field. Background technique [0002] With the development of photoelectric jamming technology, stealth technology and anti-radiation missile technology, a single guidance method is difficult to adapt to the complex battlefield needs in the future due to the limitation of its own physical characteristics. The infrared guidance system cannot measure distance and speed, and is easily affected by the nature of the target, the degree of thermal radiation contrast between the target and the background, and the climate. The resolution is poor, the end cannot be two-dimensionally imaged, there is angular flicker, target recognition is difficult, it is susceptible to electromagnetic interference, and it is easy to expose itself; the laser guidance system is easily affected by clouds, fog, and smoke, and ...

Problems solved by technology

[0002] With the development of photoelectric jamming technology, stealth technology and anti-radiation missile technology, a single guidance method is difficult to adapt to the complex battlefield needs in the future due to the limitation of its own physical characteristics.

The infrared guidance system cannot measure distance and speed, and is easily affected by the nature of the target, the degree of thermal radiation contrast between the target and the background, and the climate. Poor resolution, no two-dimensional imaging at the end, corner flicker phenomenon, difficult target recognition, susceptible to electromagnetic interference, and easy to expose itself; laser guidance system is easily affected by clouds, fog, and smoke, and cannot be used around the clock
