Abstract

The invention discloses an optical sensing device, comprising a housing, at least one light-emitting component, at least one optical sensing component and a shading component. The inside of the housing is provided with a blackbody condition space, and the light-emitting component projects a beam towards the blackbody condition space. The optical sensing component is arranged on the housing and adjacent to the blackbody condition space. The shading component is movably arranged in the blackbody condition space and has at least one end face which is contacted with the housing and provided with at least one groove. When the shading component moves to at least one shading region of the blackbody condition space, the optical sensing component is shaded by the shading component. When the shading component departs from the shading region, the optical sensing component senses the beam to send out a sensing signal.

Description

technical field [0001] The present invention relates to an optical sensing device, in particular to an optical sensing device with high sensing sensitivity. Background technique [0002] In daily life, in order to grasp the tilt angle or displacement of an object, various sensors are usually used, and these sensors usually include a horizontal displacement sensing function, a vertical displacement sensing function or an inclination angle sensing function. In practice, these sensors usually use many sensing technologies, such as optical sensing technology, acoustic wave sensing technology or electrical sensing technology. Among them, due to the advantages of fast sensing speed, the optical sensing technology is gradually applied to the production of high-sensitivity sensing applications. [0003] On this premise, two representative existing optical sensing technologies will be listed below for specific description. see Figure 1 to Figure 3 , figure 1 It is a three-dimens...
