摘要:
Solar spectral irradiance (SSI) measurements are important for solar collector/photovoltaic panel efficiency and solar energy resource assessment as well as being important for scientific meteorological/climate observations and material testing research. To date such measurements have exploited modified diffraction grating based scientific instruments which are bulky, expensive, and with low mechanical integrity for generalized deployment. A compact and cost-effective tool for accurately determining the global solar spectra as well as the global horizontal or tilted irradiances as part of on-site solar resource assessments and module performance characterization studies would be beneficial. An instrument with no moving parts for mechanical and environment stability in open field, non-controlled deployments could exploit software to resolve the global, direct and diffuse solar spectra from its measurements within the 280-4000 nm spectral range, in addition to major atmospheric processes, such as air mass, Rayleigh scattering, aerosol extinction, ozone and water vapour absorptions.

A photoreception device includes: a substrate; a photoreceptor element including a photoreceptor portion upon an upper surface thereof and a lower surface thereof is mounted upon the substrate; and an insulating resin mass that contains a flat upper surface and an opening that exposes the photoreceptor portion of the photoreceptor element, that is formed upon the substrate to be thicker than thickness of the photoreceptor element, and that adheres closely against side surfaces of the photoreceptor element, the side surfaces surrounding the photoreceptor element. The insulating resin mass contains a step portion that is provided to a height between the flat upper surface thereof and the upper surface of the photoreceptor portion; and the step portion extends parallel to at least one pair of mutually opposed side surfaces of the photoreceptor element, at a periphery of the opening.

Observation is performed using a clear image such that halation is prevented from occurring on an image generated due to light with strong intensity such as regular reflection light on the surface of an object. There is provided a scanning endoscope (1) including an optical scanning unit (10) in which an angle at which illumination light is emitted from a leading edge of an insertion portion (2) is changed to scan the emitted illumination light on an object, a plurality of light receiving portions (13) which is circumferentially spaced apart at the leading edge of the insertion portion 2 and receives return light returning from the object as a result of the optical scanning unit (10) scanning the illumination light, a light detection unit (14) that detects the intensity of the return light received by the light receiving portion (13), a return light selection unit (15) that selects the return light whose intensity, which is detected by the light detection unit (14), is equal to or smaller than a predetermined threshold, and a storage unit (5) that stores the intensity of the return light selected by the return light selection unit (15) in association with the position where the optical scanning unit (10) scans the illumination light.

There is provided an infrared sensor and a holder which is capable of preventing optical filters from being contaminated by adhesives used to fix filters to the detection element (infrared sensor element). A holder 20 included in an infrared sensor includes accommodation parts 21a and 21b that accommodate optical filters, recess parts 23a and 23b that are provided on the opposite surface 20a of the holder 20 which faces the to the infrared sensor element and are placed apart from the accommodation parts 21a and 21b, a groove 25a that is provided on the opposite surface 20a and is placed between the accommodation part 21a and the recess part 23a, and a groove 25b that is provided on the opposite 20a and is placed between the accommodation part 21b and the recess part 23b. The depth d2 of each of the grooves 25a and 25b is greater than the depth d1 of each of the recess parts 23a and 23b. In a process of adhering the infrared sensor element to the holder 20, an adhesive is applied to the recess parts 23a and 23b.
摘要:
An image forming apparatus includes a reflecting mechanism, a light receiving element and a restricting mechanism. The reflecting mechanism reflects a light beam such that the irradiation point of the light beam moves in a predetermined scanning direction. The light receiving element is arranged in a movement plane defined by the light beam reflected by the reflecting mechanism, and the light receiving element outputs a light reception signal for adjusting the irradiation timing of the light beam in accordance with reception of the light beam reflected by the reflecting mechanism. The restricting mechanism positions the light receiving element relative to the movement plane.
