Abstract: An optical navigation device, such as an optical navigation joystick or mouse, includes an internal redirector which may be separate or formed from material of a touch surface of the optical device. The redirector is disposed at an angle with respect to a plane of the touch surface, operative to reflect light which would otherwise strike the touch surface at a low angle and be internally reflected. The light may be reflected in a direction away from a light sensor of the device, reducing sensed internally reflected light, or may be reflected into the touch surface at a higher angle, potentially increasing a quantity of good signal. The redirector may also include portions which block light directly emitted from a light emitter, or reflected off other surfaces of the navigation device.

Abstract: A variety of methods and systems are described that relate to reducing optical noise. In at least one embodiment, the method includes, emitting a first light having a selected wavelength from a light source, receiving a reflected first light onto a phosphor-based layer positioned inside a receiver, the reflected first light being at least some of the emitted first light that has been reflected by an object positioned outside of a desired target location. The method further includes, shifting the wavelength of the received reflected first light due to an interaction between the received reflected first light and the phosphor-based layer, and passing the received reflected first light with respect to which the wavelength has been shifted through a light detector without detection.

Abstract: New systems for characterizing laser beams, using measurements performed on light which has been Rayleigh scattered from the beam. Different implementations are used for beam profiling, using images of the Rayleigh scattered light, and for laser beam power measurement, using the integrated Rayleigh scattered light. Both of these implementations can be applied to laser beams having high powers, since the measurements do not require insertion of any element into the beam itself, but rather depend on light scattered laterally from the passing beam. The measurements can thus be termed “non contact” measurements, in contrast to prior art methods which require an element inserted into the beam. The systems use Rayleigh scattering from the laser beam passing through ambient air, such that no special scattering chambers or liquids are required for the measurements. Special cancellation algorithms or filters are used to discriminate from light arising from scattering from dust particles.

Abstract: Provided is a photodetection device which is small in size and has excellent sensitivity. The photodetection device (10) puts cathode terminals of photodiodes (1 and 2) having different spectral characteristics, or a photodiode (1) provided with an optical filter and a photodiode (2) provided with a light shield layer, into an open end state, and detects light intensity of a desired wavelength region according to a difference in electric charges that have been stored in those photodiodes in a given period of time. Since the photodiodes 1 and 2 store electric charges, even if a photocurrent is small, it is possible to store the photocurrent to obtain the electric charges required for detection, permitting achievement of downsizing and high detection performance of the semiconductor device on which the photodiodes 1 and 2 are formed. It is also possible to realize a wide dynamic range by making the electric charge storage time variable according to the light intensity, to suppress electric power consumption by intermittently driving an element required for differential detection at the time of differential detection, and to reduce an effect from flicker by averaging the output.
