Abstract: A radiation detector, including, a photodiode, has improved uniformity of sensitivity over the field of view because the receiving surface is provided by an optical diffusing layer, and the field of view is defined by a baffle arrangement, each internal surface of whichy is reflective. The baffle arrangement also defines a volume and the diffusing layer conforms to a part of the volume adjacent to the apex thereof. The diffusing layer may be provided by material, initially in liquid form, solidified in situ within the baffle arrangement. The receiving surface may be provided within a receiving head of the detector, spaced from the photodiode. Radiation may be transmitted from the receiving surface, whether part of a separate receiving head or not, to the photodiode by an optical fibre. An assembly of four consituent detectors, each having three orthogonally arranged mirrors, may together define a hemispherically shaped volume.

Abstract: An optoelectronic module that includes a reflectance member which exhibits mitigated or eliminated fan-out field-of-view overlap can be concealed or its visual impact minimized compared to a host device in which the optoelectronic module is mounted. In some instances, the reflectance member can be implemented as a plurality of through holes and in other instances the reflectance member may be a contiguous spin-coated polymeric coating. In general, the reflectance member can be diffusively reflective to the same particular wavelengths or ranges of wavelengths as the host device in which it is mounted.

Abstract: Demultiplexing systems and methods are discussed which may be small and accurate without moving parts. In some cases, demultiplexing embodiments may include optical filter cavities that include filter baffles and support baffles which may be configured to minimize stray light signal detection and crosstalk. Some of the demultiplexing assembly embodiments may also be configured to efficiently detect U.V. light signals and at least partially compensate for variations in detector responsivity as a function of light signal wavelength.

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.
