Embodiment Construction

[0168] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0169] In modern society, many industries and fields use fingerprint identification equipment to collect human fingerprints for identification. In the process of fingerprint collection and comparison, the reading of fingerprint images (or fingerprint image collection) is very important. This is due to fingerprint identification equipment High requirements for fingerprint clarity, etc., so the accuracy of fingerprint imaging is very import...

Abstract

The invention discloses an optical imaging device as well as a manufacturing method and application thereof. The optical imaging device comprises an identification carrier, a darkroom shell, an image sensing device and a light source, wherein the identification carrier is provided with a transparent object space identification area; the darkroom shell forms a darkroom and has a through hole which is communicated with the darkroom; the image sensing device comprises an image sensor which is mounted in the darkroom; the light source is mounted outside the darkroom shell; and when an identification object is placed in the object space identification area, an emission light ray emitted by the light source emits to the object space identification area and further reaches the surface of the identification object to be reflected, and then passes through the through hole to be projected to the image sensor, so that the identification object is imaged through the optical imaging system via a pin-hole imaging principle.

Description

Technical field [0001] The present invention relates to an imaging device, in particular to an optical imaging device established by the principle of small hole imaging and its manufacturing method and application. Compared with the prior art optical imaging system, the optical imaging device collects objects. When imaging, there is no need to be equipped with optical elements such as lenses, prisms, etc., so that the height of the optical imaging device is significantly reduced, and further, the optical imaging device can be applied to electronic equipment that pursues thinness and miniaturization. Medical equipment and other fields. Background technique [0002] User identification technology is not uncommon for electronic devices. For example, a relatively popular way of user identification is to enter a combination of numbers or letters as a password on an electronic device, and compare it with the password pre-stored in the electronic device, which can identify the legitima...
