Abstract:
A solar sensor that utilizes a blocking element and curved reflective element between the sun and a photo-sensitive electronic device to provide high signal levels and the ability to shape the angular response of the overall sensor. A particular angular response can be achieved by combining the attenuating affects of the blocking element with the increased response affects of the curved reflector. These two elements may be combined into one physical structure, or may be separate. Further, the present invention contemplates the use of multiple blocking elements and multiple reflectors.
Abstract:
Electronic displays encounter visibility issues due to varying ambient light conditions. An ambient light sensor can be provided to sense ambient light and dynamically adjust display brightness to compensate for changes in ambient light. A wave guide for improving angular response in a light sensor is provided.
Abstract:
The proposal is for a sensor (1) to detect electromagnetic radiation with a detector (3) to detect the radiation in which the dependence of the sensor signal on the direction of incidence of the radiation impinging on the detector is very low. The sensor comprises a lens or lens system (2) with a positive focal length arranged in the beam path in front of the detector. The detector is arranged in the beam path in front of the focal point produced when radiation impinges in the peripheral region (11) of the lens or lens system at an angle of incidence of zero degree. The arrangement and sensitivity ranges of the detector are such that, when radiation impinges at an angle of incidence of zero degree, only a part of the radiation impinging through the lens or lens system contributes towards detecting the radiation.

PROBLEM TO BE SOLVED: To provide a sun sensor including reflective factor for converting angle response. SOLUTION: This solar sensor uses both shield factor and curved reflective factor between sun and a photosensitive electron device so that high signal level of the whole sensor and formation capability of angle response are provided. A specific angle response may be feasible by combining damping effect of the shield factor with increasing response effect of the curved reflector. These two factors may be either combined as one physical structure or a separate body each other. Additionally for this invention, a plurality of shield factors and reflectors are also intended to be used. COPYRIGHT: (C)2005,JPO&NCIPI
Abstract:
PURPOSE:To correct deviation of light receiving section of light receiving angle characteristic from the cosine law where the light receiving angle is large, by cutting annular grooves on a light diffusing plate to provide light shielding films on inclined faces of the grooves. CONSTITUTION:The incident surface of a light diffusing plate 1 is made plane while a plurality of annular grooves are cut on the inner surface side of a light receiving section. Light shielding films are provided on the inclined surfaces of the grooves and light incident into the light receiving section is diffused with the plate 1 and converted 5 to electricity gradually through a dimmer plate 3 and a visual sensitivity correction filter 4. Here, normal transmission component x1 of the light (x) from the direction smaller in the light receiving angle passes the plate 1 at the shortest distance and attenuated being reflected with the light shielding film on the back of the plate 1. The diffusive transmission component x2 of the incident light (x) is emitted reaching the surface with no light shielding film being diffused through the plate 1. On the other hand, the normal duffusion component y1 of the light (y) from the direction larger in the light receiving angle is emitted reaching the surface with no light shielding film being diffused through the plate 1. The plate 1 thus arranged makes the normal transmission component y1 attenuate less than x1 through the plate 1. This permits the correction of deviation in the light receiving angle characteristic from the cosine law where the light receiving angle is large.
