WIPO Patent Application WO/2016/112864

Kind Code:

A1

Abstract:

An optical imaging apparatus (100J, 100K, 100L, 100S) built by using a pinhole imaging principle, a manufacturing method therefor and applications thereof. The optical imaging apparatus comprises: an identification carrier (12, 12A) which has a transparent object identification area (121, 121A); a darkroom housing (111, 111A), the darkroom housing (111, 111A) forming a darkroom (110, 110A) and having a through-hole (1111, 1111A), the through-hole (1111, 1111A) being connected to the darkroom (110, 110A); an image sensing apparatus (14, 14A) which comprises an image sensor (141, 141A), the image sensor (141, 141A) being installed in the darkroom (110, 110A); and a light source (13, 13A), the light source (13, 13A) being installed outside the darkroom housing (111, 111A). When an identification object is placed in the object identification area (121, 121A), an emitted light generated by the light source (13, 13A) is emitted to the object identification area (121, 121A) and is further reflected after reaching a surface of the identification object, and then the emitted light is projected to the image sensor (141, 141A) through the through-hole (1111, 1111A), so that the identification object is imaged by means of the optical imaging system (10, 10A) by using the pinhole imaging principle.
