Dual-mode multi-purpose continuous zoom optical system

Abstract

The invention discloses a dual-mode multipurpose continuous zooming optical system comprising a driving mechanism and a diaphragm. The dual-mode multipurpose continuous zooming optical system also comprises a front fixed lens group, a zooming lens group, a compensating lens group, an aberration stable lens group and an optical filter which are arranged from the left to the right in turn. The left side of the front fixed lens group is an object plane. The right side of the optical filter is the focal plane of the dual-mode multipurpose continuous zooming optical system. The front fixed lens group, the zooming lens group, the compensating lens group, the aberration stable lens group and the optical filter are coaxial in central axis. The driving mechanism drives the zooming lens group, the compensating lens group and the aberration stable lens group to linearly move in a forward-and-backward direction in the optical axis direction of the dual-mode multipurpose continuous zooming optical system to realize continuous zooming. The total length of the dual-mode multipurpose continuous zooming optical system is constant in the process of continuous zooming. The dual-mode multipurpose continuous zooming optical system is an optical system which is small in size, compact in structure and particularly suitable for an optoelectronic pod and can realize the function of continuous zooming and has two working modes of high-definition video photographing and ultrahigh-definition photographing imaging.

Description

technical field [0001] The present invention relates to a continuous zoom optical system suitable for television camera or photo, especially for the optical system of photoelectric pod. Specifically, the present invention relates to an optical system design capable of optical fog penetration and imaging under low-illumination conditions, capable of realizing continuous zooming, and having two working modes of high-definition video camera and ultra-high-definition camera imaging. Background technique [0002] In the prior art, there are relatively mature pod imaging devices using TV cameras and infrared thermal imaging cameras, and pod devices with single TV cameras or infrared thermal imaging cameras. The field of view of the infrared camera is small and the resolution is low, it is difficult to confirm the details of the target at a long distance, and its function is not perfect; in order to make up for the above shortcomings, the existing technology has adopted a TV camera...

Problems solved by technology

[0006] However, each of the above-mentioned patents or equipment adopts the design scheme of integrating the TV camera and the digital camera in different apertures, which increases the volume of the entire pod imaging device and increases the difficulty of integration of each imaging subsystem. Moreover, the various types of pods None of the digital cameras in the device have a continuous zoom function, and cannot realize continuous zoom imaging detection of the target area
