Abstract: An optical detection system includes a marker product and an optical encoding device. The marker product includes a substrate and at least one structural portion. The structural portion has a first surface, a second surface and a dividing axis. The first surface and the second surface are arranged on opposite sides of the dividing axis. A sidelong direction aligning the first surface with the second surface is parallel to a moving direction between the optical encoding device and the marker product. The optical encoding device is disposed adjacent by the marker product. The optical encoding device includes an optical projector and an optical encoder. The optical projector is configured to project the optical detecting signal onto the marker product. The optical encoder is configured to receive an optical reflecting signal from the marker product and encode intensity variation of the optical reflecting signal into digital data.

Abstract: An electronic apparatus includes a structure and an optical navigation circuit. A first end of the structure is located inside the electronic apparatus and its second end corresponds to a user's control. The structure can be moved forward/backward in a specific direction and/or rotated in another direction. The optical navigation circuit captures reflection of a light emitting to the structure to detect displacement of the image along a specific axis of the structure, and determines the user's operating behavior as a specific operation according to a change of the sensed displacement of the image.

Abstract: A control system, a mouse and a control method thereof are provided. The control system comprises a dongle and the mouse. The dongle is wiredly connected to a host and has a first light source for emitting a first light. The mouse is wirelessly connected to the dongle and has a transmitter, a second light source for emitting a second light, an optical sensor and a processor. The optical sensor senses the first light at a first time interval to generate a first sensing signal and then also, senses the second light at a second time interval to generate a second sensing signal. The processor generates a first control signal and a second control signal according to the first sensing signal and the second sensing signal, respectively, and transmits them to the dongle via the transmitter so that the host receives the first and second control signals via the dongle.

Abstract: There is provided an optical raindrop detector including a light source, a light guide, an image sensor and a processing unit. The light source alternatively emits light with different brightness values. The light guide has an incident surface, a detection surface and an ejection surface, wherein the light source emits incident light into the light guide via the incident surface, and a plurality of microstructures are formed on the ejection surface to reflect the incident light to become scattered light toward the detection surface. The image sensor receives reflected light formed by raindrops in front of the detection surface reflecting the scattered light to penetrate the light guide and eject from the ejection surface, and generates image frames corresponding to the different brightness values of the light source. The processing unit calculates differential images of the image frames to accordingly identify rain intensity.
