Abstract: An optical sensor device includes an optical filter, an optical element, and an optical sensor that includes a plurality of sensor elements. The optical filter is configured to pass, to the optical element, first light beams that are associated with a first subrange of a spectral range and that impinge on the optical filter within a first incidence angle range; and to pass, to the optical element, second light beams that are associated with a second subrange of the spectral range and that impinge on the optical filter within a second incidence angle range. The optical element is configured to cause, based on receiving the first light beams, the first light beams to be directed to a first region of an optical sensor; and to cause, based on receiving the second light beams, the second light beams to be directed to a second region of the optical sensor.

Abstract: A receiver, method, terminal device, visible light transmissive structure and system for decoding light signals and light signals received in an area of overlap of light rays emanating from different lighting devices, each transmitting unique ID data. Light rays (45, 46, 47) entering the receiver (39) are optically spread apart in longitudinal direction (x) of an array of photodetectors (21). The thus spread light rays (45a, 46a, 47a) are optically diverged and spread further over the radiant active surface (29) of a particular photodetector (22-28), thereby optimizing the amount of light received at a respective photodetector (22-28).

Abstract: An optical sensor device comprises a first and a second optical sensor arrangement. In the first optical sensor arrangement at least one optical sensor structure measures the incidence angle of incoming light that is approximately on the main beam axis of a light source. The second optical sensor arrangement comprises at least one optical sensor structure with at least one optical sensor, at least two metal layers and opaque walls optically isolating the optical sensor. An evaluation circuit provides an output signal of the second optical sensor arrangement under the condition that the incidence angle measured by the first optical sensor arrangement lies within a set interval.

Abstract: 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 vapor absorptions.
