Multidirectional lens automatic adjustment device

Abstract

The invention provides a multidirectional lens automatic adjustment device and belongs to the field of photoelectric detection, which solves the problems in the prior art that existing devices can only meet single-orientation or manual-adjustment requirements and cannot realize the multidirectional and real-time adjustment of lenses. The above multidirectional lens automatic adjustment device comprises a transmission mechanism, a stator, a rotor, a sleeve, a main elastic element, a lens holder, a lens, a main moving rod, an auxiliary moving rod, a feedback element, an auxiliary elastic element, a controller and the like. The feedback element feeds back the real-time displacement parameters of the lens and other elements in the system to the controller. The controller controls the rotation of the rotor. At the same time, the controller drives the auxiliary moving rod to rotate inside the helical groove of the lens holder so as to realize the angular displacement of the lens. The controller controls the transmission mechanism to drive the main moving rod to move axially along the axis thereof so as to realize the linear displacement of the lens. According to the technical scheme of the invention, the angular displacement of a to-be-tested lens is realized, and the linear displacement of the lens can also be realized. Meanwhile, the lens is controlled in real time by the feedback element and the controller. Therefore, the multidirectional and real-time adjustment of the lens in the optical system can be realized.

Description

technical field [0001] The invention belongs to the field of photoelectric detection, and in particular relates to a multi-directional lens automatic adjustment device. Background technique [0002] In the field of photoelectric detection, for different target objects, in order to obtain higher imaging quality and higher tracking accuracy, it is often necessary to adjust the angle of some lenses and the distance between the lenses in the optical system during the work process. [0003] At present, the lens adjustment methods commonly used in the optical system in the field of photoelectric detection mainly include: 1) gasket adjustment. That is, during the initial installation and debugging process, the angle and distance of the lens are adjusted by adjusting the thickness of the gasket according to the determined parameters. After the adjustment is completed, it will not change. This method is a one-time adjustment. During the working process, when the optical system is ou...

Problems solved by technology

Although this adjustment method can improve the adjustment efficiency and adjustment accuracy, it still cannot be adjusted in real time when the optical system is working.

[0004] In addition, there are some single-degree-of-freedom lens automatic adjustment devices, but they can only meet the adjustment requirements of a single direction, and their application is limited when multi-directional lens adjustment is required.
