Optical imaging system

Technical Field

The invention relates to the technical field of optical imaging, in particular to an optical imaging system.

Background

Optical imaging is generally performed by changing the optical path using lenses or mirrors, such as telescopes, microscopes, etc., and such imaging schemes are well established. However, due to the characteristic that light rays travel along a straight line, in the current imaging scheme, objects cannot block the straight-line travel path of the light; when obstructions are present in the light path, the device can only be made very large, leaving room for the light path to overcome the occlusion problem.

In the prior art, in order to avoid the overlarge volume of the equipment, a researcher respectively arranges a camera and a display screen at two ends of a shelter, so that light rays on the back of the shelter are displayed on the display screen on the front of the shelter, and the light rays can cross the propagation of the shelter. However, the image presented by this mode is not the original ray, but is subjected to two-step intervention of image acquisition and imaging, so that the definition is influenced by the performance of a camera and a display screen, and the problems of angle deviation and various distortions exist. In addition, the power supply is needed in the mode, and the introduced electric appliances such as a camera, a display screen and the like also improve the complexity, the maintenance difficulty and the like of the whole imaging system.

Disclosure of Invention

The invention aims to provide an optical imaging system aiming at overcoming the technical defects in the prior art, and aims to solve the technical problem that the imaging system can only be increased in size to avoid blocking an optical path in the prior art.

Another technical problem to be solved by the present invention is to provide a mode for transmitting light path across a shielding object by means of camera shooting and display screen imaging, which has low definition and distorted picture and needs to match power supply and circuit.

In order to achieve the technical purpose, the invention adopts the following technical scheme:

an optical imaging system comprises a collection end, a display end, an optical fiber, an incident site and an emergent site, wherein the collection end is provided with a plurality of incident sites, and the display end is provided with a plurality of emergent sites; the arrangement positions of the plurality of incident sites on the acquisition end correspond to the arrangement positions of the plurality of emergent sites on the display end one by one; an optical fiber is connected between the incident point and the corresponding emergent point.

Preferably, both the acquisition end and the display end are in the shape of planar panels. It should be noted that the technical feature is only a preferred technical solution of the present invention, and as long as the acquisition end and the display end satisfy a one-to-one corresponding positional relationship, the acquisition end and the display end can adopt any configuration including a plane and a curved surface to implement the present invention.

Preferably, the automobile display device further comprises an automobile A column, wherein the collecting end is fixedly connected to the outer side of the automobile A column, and the displaying end is fixedly connected to the inner side of the automobile A column. It should be mentioned that the a pillar of the vehicle is only an optional application scenario of the present invention, and the present invention can be applied to any shelter structure without changing the basic technical principle of the present invention.

Preferably, the optical fiber is bent, and the optical fiber passes around the car a-pillar from a side of the car a-pillar.

Preferably, the display device further comprises a magnifying lens, and the magnifying lens is located on the light ray emergent path of the display end. It should be mentioned that, the emergent light of the display end is interfered by the magnifier in the preferred technical scheme, so as to obtain a clearer visual field; it is merely a preferable embodiment of the present invention, and is not an element of the present invention.

It is known that a display is formed by combining small pixel points, and finally a complete picture is formed. The optical fibers are arranged on the panel in order and tightly (one optical fiber is a pixel point), and the transmission of pictures is completed through the acquisition end and the display end. As shown in fig. 1, the collection end and the display end are completely in one-to-one correspondence, and each pixel point transmits a picture from the collection end to the display end through an optical fiber. The light angles are identical except for the identical position, so that the display end can see the identical picture as the collection end. As shown in fig. 1, the device can be made very small and flexible, since the fiber can be bent almost arbitrarily.

In the invention, the panel plays a role in fixing the position and direction of the optical fiber, no special requirement is provided for the connection mode, and any process in the prior art can achieve the effect required by the invention.

The beneficial effects of the invention are reflected in the following aspects: the invention has low cost and convenient maintenance, and is a pure optical scheme without power supply. The volume is reduced, the occupied area is small, a fixed straight line is not needed, and the device can be used for transmitting a longer distance. The visual field is wide, can change along with the visual angle, can not only fix and shoot a direction with the camera scheme.
