Turning high-resolution onboard zoom pick-up lens and control method thereof

Abstract

The invention relates to a turning high-resolution onboard zoom pick-up lens and a control method thereof. A front placing group A with the positive focal power, a zooming group B with the negative focal power, a compensation group C with the positive focal power, an iris diaphragm assembly D, a rear placing group E with the positive focal power and a turning reflecting mirror group F are sequentially arranged in an optical system of the lens in the light incidence direction. According to the turning high-resolution onboard zoom pick-up lens and the control method thereof, a light path is turned by 180 degrees, the small, exquisite and compact appearance structure is achieved, and the pick-up lens has the advantages of being long in focus, large in field angle, high in resolution, suitable for the onboard camera shooting field and the like; the focus control function, the continuous zooming control function, the manual / automatic dimming function and the image output function can be achieved through an electric focusing mechanism, an electric zooming mechanism, an electric dimming mechanism and the like.

Description

technical field [0001] The invention relates to the field of video camera technology, in particular to a turning type high-resolution airborne zoom camera lens and a control method thereof. Background technique [0002] The camera lens suitable for airborne monitoring requires a long observation distance, a large observation range, high definition, small size, and light weight. It can not only perform panoramic observation of a large area with a small magnification, but also perform a zoomed-in observation of a small area with a large magnification. . However, the traditional conventional zoom lenses generally have shortcomings such as short focal length, poor image quality, large shape and volume, and are not suitable for airborne environments. Moreover, the existing airborne zoom lens is limited by the use environment, has a large shape and volume, and has poor image quality, which limits the observation capability. Contents of the invention [0003] In view of the def...
