Abstract: The inventive sensor device includes a support structure, a sensing element mounted on the support substrate for sensing optical radiation and generating an electrical output signal in response thereto, and an encapsulant encapsulating the sensing element on the support structure. The encapsulant being configured to define a lens portion for focusing incident optical radiation onto an active surface of the sensing element, and an optical radiation collector portion surrounding the lens portion for collecting and redirecting optical radiation that is not incident the lens portion onto the active surface of the sensing element. The collector portion may be a parabolic reflector that reflects incident light by total internal reflection. The sensor device may be incorporated into an assembly including a diffuser positioned across an aperture, and/or may be incorporated into a vehicle accessory such as a rearview mirror assembly.

Abstract: A color measurement device designed for use at various stages of an industrial process is provided. The device offers enhanced insensitivity to ambient light, measurement depth variations, and/or ambient or environmental temperature variations. The device may be embodied as an LED-based, non-contact color measurement spectrophotometer. Over- illumination in full-spectrum of the target object facilitates effective color measurements over varying depths of view. Collected light is measured at discrete wavelengths across the entire visual spectrum. The hardened, rugged design and packaging of the measurement device allows color measurement to be performed at various stages of industrial processes wherein the device can add value by enabling enhanced detection of color errors.

Abstract: In a light (optical) beam steering/sampling system, a matrix inversion control technique is used to decouple the operation of the actuators which drive the steering mirrors. The control technique uses two virtual variables, each having an associated independent feedback loop operating in a non-cross-coupled manner, each variable being associated with one of the two steering mirrors.

Abstract: A system is provided for tracking a free-space optical communications beam. The incoming beam is split by a beam splitter (24). One portion of the incoming beam is focused onto a high-speed photodetector (26). Another portion of the incoming beam is passed through a target pattern optical element. A resulting target pattern is formed on a two-dimensional active pixel sensor array. The alignment of the system can be adjusted based on the position of the target pattern on the sensor array.

Abstract: A photosensor arrangement produces an electrical signal responsive to the position of a source of light by employing a mask (15) situated at a predetermined height above a plurality of photodetectors (D1,1), (D1,2), (D2,1), (D2,2) such that as the sun moves with respect to the apparatus, a shadow is cast which is responsive to the location of the sun. An apparatus constructed in accordance with the invention has a plurality of photosensors, each having a respective substantially planar light-sensitive surface for receiving the input light from the sun over a predetermined range of positions. In a preferred embodiment where compactness is desired, the planar light-sensitive surfaces are arranged in a substantially coplanar relationship with respect to one another. The light mask, which has opaque (16) and transparent (17) portions, is arranged to overlie the substantially planar light-sensitive surfaces for determining the position-responsive sensitivity characteristic of the apparatus. In certain embodiments, a diffuser is interposed between the light mask and the photodetectors. The response characteristic of the apparatus can be determined by geometric analysis, or empirically using values which may be stored in a look-up table.

Abstract: A receiver for a radiated electromagnetic signal includes elements 26, 22 that respectively transmit a high percentage and a low percentage of the incident signal, in combination with a detector 24. The device is adapted for mounting on or near a horizontal surface, such as a ceiling. The signal is preferably in the infrared region of the spectrum. The receiver provides non-electronic gain control and, when the high-transmission element 26 passes the signal wavelength preferentially over the other wavelengths, it also provides improved noise immunity.
