Flexible adjustable lens with multilayer structure and zooming optical system

Abstract

The invention discloses a flexible adjustable lens with a multilayer structure and a zooming optical system. A rigid lens, optical liquid, a multichannel glass inner lens and a transparent elastic film are used as refraction media to form a multilayer multichannel flexible adjustable lens. The zooming optical system comprises a pre-refraction lens group, a diaphragm, a flexible adjustable zooming lens group and a back refraction lens group which are coaxially successively arranged from the left to right. The flexible adjustable zooming lens group comprises two flexible adjustable lenses. In a zooming adjusting process, an annular ultrasonic motor squeezes the external surface of the flexible adjustable lenses through a transmission press ring so as to change the focal lengths of the flexible adjustable lenses. By cooperatively adjusting the focal lengths of the flexible adjustable lenses, continuous zooming adjustment of the system is achieved. The lens and the system are advantaged by compact structure, flexible control, stable optical axis, large adjustment range and high imaging quality, and can be used in all kinds of modern optical imaging systems and robot vision systems.

Description

technical field [0001] The invention relates to a bionic vision imaging system, in particular to a flexible adjustable lens and variable power optical system with a multi-layer structure. Background technique [0002] With the development and progress of technology, people have higher and higher requirements for the integration, portability and focusing ability of visual imaging equipment. The optical lens and its variable magnification imaging module are the key parts of the visual imaging equipment, which have an important impact on the structural composition, adjustment characteristics and imaging quality of the visual imaging system. [0003] The traditional optical zoom system uses many different concave-convex lenses to form multiple optical lens groups, uses the drive motor to precisely control the mechanical position of each lens group, and realizes the focal length and magnification of the system by changing the optical interval of each lens group. adjust.

Problems solved by technology

However, the use of liquid as the main optical liquid is not conducive to maintaining the stability of the optical axis and the reliability of the system, and the use of liquid crystal materials is often affected by the polarization of liquid crystal molecules, making it difficult to maintain ideal imaging quality

In addition, optical systems designed with new adjustable lenses often have shortcomings such as single refractive medium, less design freedom, and unsatisfactory imaging quality, making optical systems based on adjustable lenses unable to compete with traditional optical systems using rigid lenses. system comparison
