Abstract: An optical detecting device is utilized to determine a relative position of a reference object or a light source according to an optical reflecting signal reflected from the reference object via an optical detecting signal emitted by the light source. The optical detecting device includes a light penetrating component, at least one light tight structure and an optical detecting component. A focal length of the light penetrating component is greater than a predetermined distance. The light tight structure is located on a region correlative to the light penetrating component. The optical detecting component is disposed by the light penetrating component and spaced from the light penetrating component by the predetermined distance. The optical reflecting signal is projected onto the optical detecting component through the light penetrating component to form a characteristic image via the light tight structure, and the characteristic image can be used to determine the relative position.

Abstract: An optical navigation device has a light-emitting unit, an optical navigation chip and a cover. The light-emitting unit provides a light to a surface of a displacement generating unit. The optical navigation chip has a sensing array, but excludes any optical lens for focusing a reflected light. The sensing array disposed opposite to the surface of the displacement generating unit receives the reflected light which the light provided by the light-emitting unit is reflected from the surface of the displacement generating unit. The cover has a first surface and a second surface, and an angle is formed between the cover and the optical navigation chip, to prevent another reflected light from the surface of the first surface of the cover from entering the sensing array. Particularly, the angle formed between the cover and the optical navigation chip is from 10 degrees to 15 degrees.

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: The present disclosure illustrates an optical navigation chip. The optical navigation chip is disposed on an optical navigation module. The optical navigation module includes a light-emitting unit. The light-emitting unit provides a light beam to irradiate a surface of a displacement generating unit. The light beam has a low divergence angle to reduce scattering. The optical navigation chip includes a sensing array and a displacement calculating unit. The sensing array is disposed corresponding to the surface. The sensing array receives a reflected light beam which the surface reflects, and captures an image once every capturing interval based upon the reflected light beam. The displacement calculating unit calculates a relative displacement between the optical navigation chip and the surface according to the images.
