Abstract

The invention discloses an optical induction device with anti-static elements. The optical induction device comprises a shell, at least one luminescent element, a shielding element, at least one anti-static element, and at least one optical induction element. The shell is internally provided with a blackbody condition space and comprises a luminescent chamber, a light-shielding chamber and at least one optical induction chamber. The luminescent element projects a light beam towards the luminescent chamber. The shielding element is movably limited in the light-shielding chamber, and generates a static power during the moving. The anti-static element is arranged in the light-shielding chamber so as to conduct and ground the static power. The optical induction element is arranged in the optical induction chamber and induces the light beam so as to transmit an induction signal.

Description

technical field

[0001] The invention relates to an optical sensing device, in particular to an optical sensing device with an antistatic element. Background technique

[0002] In daily life, in order to grasp the inclination 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, since the optical sensing technology has the advantages of fast sensing speed, it is gradually applied to the production of high-sensitivity sensing applications.

[0003] In most of the optical sensing devices produced by the prior art, a black body conditional space is enclosed in a casing, and a light emitting element, a shielding element and at ...
