Abstract: A back side incident type image pickup sensor in which lowering of spatial resolution is eliminated and influence of stray light is removed is provided. Electric circuits including a driver circuit for driving a photoelectric conversion portion and a signal processing circuit for processing signals from the photoelectric conversion portion are each placed on the front side of a single crystal silicon substrate at a given distance in the horizontal direction from an opening. Influence of stray light is thus eliminated. The semiconductor substrate has high refractive index, thereby essentially allowing little lowering of spatial resolution. Lowering of spatial resolution is further prevented if the substrate is thinned.

Abstract: An imaging system for use in a vehicle headlamp control system including an opening, an image sensor, a red lens blocking red complement light between the opening and the image sensor, and a red complement lens blocking red light between the opening and the image sensor. Each lens focuses light onto a different subwindow of the image sensor. The imaging system allows processing and control logic to detect the presence of headlamps on oncoming vehicles and tail lights on vehicles approached from the rear for the purpose of controlling headlamps. A light sampling lens may be used to redirect light rays from an arc spanning above the vehicle to in front of the vehicle into substantially horizontal rays. The light sampling lens is imaged by the image sensor to produce an indication of light intensity at various elevations. The processing and control logic uses the light intensity to determine whether headlamps should be turned on or off. A shutter may be used to protect elements of the imaging system from excessive light exposure.

Abstract: A radiant energy transducer system includes a base. The base has a diffusely reflective surface and an optical area defining a horizon district with respect to the transducer system. A mask occludes a portion of the optical area so as to present a substantially constant portion of the optical area over a range of angles above the horizon district. An electromagnetic transducer converts between radiation associated with the optical area and corresponding signals. Examples of the transducing systems provide emission of radiant energy with a tailored intensity distribution over an area illuminated by the system. Other examples of the transducing systems detect radiant energy, and the position of the mask relative to the optical area of the detector system serves to tailor the sensitivity of the detector over a field of view. The emitters and detectors can be used together, for example in a system for tracking the position of an object.

Abstract: An infrared collector for use in communications systems. The infrared collector employs a concentrator which concentrates infrared radiation received from some directions more than others. The concentrator is made of a dielectric material which is substantially transparent to infrared radiation and has a shape which is convex above a base plane determined by the top surface of an infrared radiation detector and in which any ray which connects any part of the top surface of the detector to any part of the concentrator above the base plane intersects the surface of the concentrator at an angle less than the critical angle for the material from which concentrator is made. The amount of concentration from a given direction is controlled by the curvature of the collector. The less a portion of the surface is curved, the less infrared radiation normal to the less-curved portion is concentrated. The collector may be used in environments where there is a predominant direction from which infrared noise is received in the collector which is different from the direction from which infrared communications signals are received in the collector.

Abstract: A wide field-of-view optical element 12 suitable for use in a laser warning system including a frusto-conical block of optically transparent material having a first surface 14 and a second surface 16. The first surface 14 is parallel with the second surface 16 and coaxial therewith. The radius R.sub.1 of the first surface 14 is less than the radius R.sub.2 of the second surface such that the sides of the element 12 are slanted. Reflective material is coated on the interior 17 of the first surface 14 for directing incident optical energy toward a detector 20 mounted at the second surface 16. Similarly, a reflective material is coated on the interior 18 of the second surface 16 for directing incident optical energy to the detector 20 via the first surface 14. The second reflective coating on the second surface is disposed between the outer periphery thereof and a nonzero distance R.sub.3 from the center thereof to provide an aperture at which the detector 20 may be mounted.
