Abstract

The present disclosure relates to an optical sensing module, an optical sensing accessory, and an optical sensing device. A reflective optical sensor module comprises a light source and a first encapsulant, a photodetector and a second encapsulant, an electrode and a substrate. The light source is configured to convert electric power into radiant energy and to emit light to an object surface. The photodetector is configured to receive the light from an object surface and to convert radiant energy into electrical current or voltage. The electrode is configured to detect an external circuit formed by the contact with an object surface. The optical sensing accessory and the optical sensing device comprise the reflective optical sensor module and other electronic modules to have further applications.

Description

technical field [0001] The invention relates to an optical sensing module, an optical sensing accessory, an optical sensing device and related applications. Background technique [0002] The basic principle of the reflective optical sensor module is that light is emitted from the light source and projected onto the object to be measured, and the photodetector receives and measures the amount of reflected light, calculates it and converts it into an electrical signal. Generally speaking, the light incident on the object under test can be reflected, refracted, absorbed or scattered by the object. As long as part of the reflected light, refracted light and scattered light is received by the photodetector of the optical sensor module, it can be converted into a signal and used for measurement. [0003] When calculating the signal noise ratio (Signal Noise Ratio, SNR), the above-mentioned signals corresponding to the reflected light and the scattered light are defined as the sig...
