Abstract: A method for identifying an object, an optical sensing apparatus and a system are provided. A controller of the system drives multiple light sources of the optical sensing apparatus to emit the multiple light beams with different beam angles, controls a light sensor to sense the lights reflected by the object, and performs the method for identifying the object. In the method, the light sensor is used to sense a first light emitted by a first light source with a first beam angle reflected by the object, and sense an intensity of the reflected first light. The light sensor is also used to sense a second light emitted by a second light source with a second beam angle reflected by the object and sense another intensity of the reflected second light. Therefore, the object can be identified by integrating information of the intensities obtained by the light sensor.

Abstract: An optical detecting device capable of increasing signal-to-noise ratio (SNR) and economizing power consumption is installed on a wearable device. The optical detecting device includes a base, an optical detecting component and a light emitting module. The optical detecting component is disposed on the base and has a detecting surface normal vector. The light emitting module is disposed on the base and outputs a sampling signal to project onto an external object, and the optical detecting component can receive the sampling signal reflected from the external object. The light emitting module is slanted toward the optical detecting component, and an optical axis of spatial distribution of the sampling signal and the detecting surface normal vector are crossed to form a deviated angle.
