Novel zoom lens

Abstract

The invention relates to a novel zoom lens which comprises a zoom lens. The zoom lens is composed of a condensing lens, a polarizing film, an LCOS and a CCD. The polarizing film is arranged on one side of the condensing lens, the condensing lens is composed of optically denser substances, the propagation speed of a light source in the condensing lens is smaller than that of the light source in air, and the light source enters from one side of the lens and exits from the other side of the lens. The LCOS is used as an active optical element, so that the imaging system realizes optical zooming onthe premise of not mechanically moving the optical lens part. Compared with the existing zoom lens, the novel zoom lens has the advantages of wide viewing angle and flexible and variable shooting angle; the optical zoom ratio is high, and the shooting range is wide; LCOS optical zooming is achieved, and the zooming speed is high; the realization of high resolution meets the requirements of mediumand high-end markets; and the novel zoom lens has the advantages of reasonable price, guaranteed price advantage and the like, is convenient for a user to carry, meets the requirements of medium andhigh-end video monitoring and photographic zoom lenses, and can be better combined with the existing monitoring and photographic equipment at the same time.

Description

technical field

[0001] The invention relates to the technical field of zoom lenses, in particular to a novel zoom lens. Background technique

[0002] At present, all image-capturing products on the market must be equipped with zoom lenses, especially in mid-to-high-end applications. Zoom cameras are very expensive, and to achieve ideal shooting effects, the technical requirements for operators are also relatively high.

[0003] Most of the zoom cameras on the market have complex internal structures and large sizes, resulting in heavy weight, which is not convenient for users to carry, and cannot be combined with existing monitoring and photographic equipment according to actual needs, resulting in failure to meet mid-to-high-end cameras. The requirements for video surveillance and photography zoom lenses greatly reduce the actual use effect of the corner lens, which is not conducive to the use of users, and it is impossible to achieve optical zoom without mechanically moving...

Embodiment

[0021] see figure 1 , the present invention provides a technical solution: a novel zoom lens, including a zoom lens, the zoom lens is composed of a condenser lens, a polarizer, an LCOS and a CCD, specifically, the LCOS model is MD1280, and the condenser lens There is a polarizer on one side, and the condensing lens is composed of light-dense material. The propagation speed of the light source in the condensing lens is smaller than its propagation speed in the air. The light source is incident on one side of the lens, and the Exit, specifically, it is assumed that the beam of light enters the lens from a point whose coordinate point is (x, y), and exits from approximately the same position relative to this point. That is, if the translation that occurs as light propagates inside the lens is ignored, the lens can act as a thin lens. A thin lens can delay the incident wavefront, and the size of the delayed incident wavefront is proportional to the thickness of each point of the ...
