Abstract:
The present invention provides an instrument and method for measuring total luminous flux of luminous elements, which forms an approximately uniform spatial intensity distribution by simultaneously lighting a plurality of luminous elements for measurement in an integrating sphere when comparing a total luminous flux standard lamp with the luminous elements to measure the total luminous flux of the luminous elements, thus not requiring spatial mismatch error correction.

Abstract:
A sensitive photon detection system generates an electronic photon sensor signal as a K factor times a number N photons per unit time. The system is configured by combining a separate optical amplifier with a gain factor K1 with a photo detector with a gain factor K2 such that K may be realized as the product of K1 and K2. The values of K1 and K2 are chosen to meet a predetermined K while optimizing a signal quality of the photon sensor signal. The optical amplifier may be preceded by a photon gathering device and/or a light chopping device to further optimize system performance. Further, the photon sensor signal may be further processed analog circuitry or may be digitized and processed using digital signal processing to generate an enhanced photon sensor signal with enhanced signal quality by adding gain and/or bandwidth limiting.

Abstract:
PURPOSE:To uniformly form effective visual field angle in each segment element surfaces and to remove shading phenomenon by disposing a light shielding plate in mesh shape in a visual field deciding hole of a cold seal disposed opposited to a full photoreceiving element of an infrared ray receiving element. CONSTITUTION:A light shielding partition plate 22 having a vertical surface to the light receiving surface 2c of a photoreceiving element array is arranged in combination with a mesh state made of lattice in the visual field deciding hole 4 of a cold shield 3 opposite in the prescribed height to the full photoreceiving elements of an infrared ray receiving element array 1. The width L of the plate 22, the interval D between the plates 22, and the height H of the mesh light shielding plate 21 to the surface of the photoreceiving element 2 are suitably selected to aniformly specify the effective visual field in the respective photoreceiving surface 2c. Thus, the incident light amount to the array 1 is reduced toward the potoreceiving element 2b of the peripheral end via the photoreceiving element 2a at the center as a shading phenomenon can be remarkably reduced.
Abstract:
PURPOSE:To contrive dissolution of a shading phenomenon by a method wherein the visual field determining aperture part of the cold shield for the entire light- receiving element surface of an inflared ray light-receiving element array is constituted in blind form. CONSTITUTION:The titled device is constituted in such a manner that the visual field determining aperture part 5 of the cold shield 3 facing in the prescribed height against the entire light-receiving element surface of the inflared ray light- receiving element array 1 is arranged in said aperture part 4 so that it is positioned vertical to the light-receiving surface of the array 1 and that a plurality of light-shielding partition plates 21 are arranged in parallel and orthogonally intersecting with the direction of arrangement of the array 1. The angle of visual field on each light-receiving surface of the array 1 can be uniformly prescribed by each partition plate 21 by constituting the aperture part 4 in blind form as above-mentioned. The shading phenomenon generating on the light-receiving element 2a located in the center part of the array 1 and on the light-receiving element 2b on both ends can be dissolved by properly selecting the width of the partition plates 21, the intervals between each partition plate and the height of the partition plates 21 against the element surface.
