Miniaturized high-definition fog-penetrating zoom camera lens and control method thereof

Abstract

The invention relates to a miniaturized high-definition fog-penetrating zoom camera lens and its control method. The lens is sequentially provided with a front fixed group A with a positive focal power and a zoom group B with a negative focal power. The focal power is Negative compensation group C, positive rear fixed group D and color filter lens E; the front fixed group A includes positive crescent lens A-1, positive crescent lens A-2, negative crescent lens A-3 and The first cemented group of positive crescent lens A-4 close contact; the variable power group B includes biconcave lens B-1 and the second cemented group tightly connected by biconvex lens B-2 and biconcave lens B-3; the compensation group C Including the third glued group tightly connected by the positive crescent lens C-1 and the biconcave lens C-2; The fourth cemented group, the biconvex lens D-4, and the fifth cemented group in which the positive crescent lens D-5 and the negative crescent lens D-6 are closely connected. The lens improves the resolution and improves the detection ability and clarity in rain, snow, mist and other hazy weather.

Description

technical field [0001] The invention relates to a miniaturized high-definition fog-penetrating zoom camera lens and a control method thereof, belonging to the field of optoelectronic technology. Background technique [0002] Ordinary camera lenses are limited to applications under general lighting conditions. When used in hazy weather conditions such as rain, snow, and mist, the detection range of the system will be severely reduced, especially when the signal itself is very weak, which will cause the target signal to be submerged in the In the background signal, it cannot be used normally; due to the dispersion of the glass material, the optimal image plane position is inconsistent for different wavelengths of light, which makes it difficult for the commonly used visible light band imaging lens to maintain high-quality imaging in the near infrared band; the traditional optical path When the structure is limited in shape and volume, the zoom factor is very small and the reso...
