Abstract

The invention discloses an image sensor, an optical imaging system and a manufacturing method, and relates to the technical field of optical imaging. According to the main technical scheme, the imagesensor comprises an optical fiber image transmission element and a semiconductor chip, and the optical fiber image transmission element comprises a plurality of optical fiber filaments with preset diameters and is used as a probe for collecting images and transmitting the images; the input end of the semiconductor chip is tightly connected with the first end of the optical fiber image transmissionelement and is used for converting an optical signal into an electric signal; wherein the protective cover at the input end of the semiconductor chip is removed; wherein the surface of a shot objectis close to the second end of the optical fiber image transmission element, image information is transmitted to the semiconductor chip through total reflection of the optical fiber image transmissionelement, and the semiconductor chip converts the image information into an electric signal and outputs the electric signal for imaging; according to the invention, the problems of distortion, distortion, blur or low resolution of the optical fiber image transmission element during image acquisition are avoided, and the resolution is improved.

Description

technical field [0001] The invention relates to the technical field of optical imaging, in particular to an image sensor, an optical imaging system and a manufacturing method. Background technique [0002] An industrial camera is a high-resolution color digital camera suitable for many applications, one of which is a camera containing a CCD (Charge Coupled Device, photosensitive coupling component, which is a semiconductor that can record light changes in a digital camera), so It has the advantages of strong anti-interference ability, shorter shutter time, compact structure, etc., and has been widely used in medicine, industry, communication and other industries; its working principle is that the image of the subject is focused on the CCD chip through the lens, Form a video signal output. [0003] However, there is a certain distance between the lens and the CCD chip, and the working environment of industrial cameras is relatively harsh, and the lens needs to be exposed to ...
