Abstract: Information is encoded in an image signal by exploiting spectral differences between colors that appear the same when rendered. These spectral differences are detected using image sensing that discerns the spectral differences. Spectral difference detection methods include using sensor-synchronized spectrally-structured-light imaging, 3D sensors, imaging spectrophotometers, and higher resolution Bayer pattern capture relative to resolution of patches used to convey a spectral difference signal.

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 vapour absorptions.

Abstract: A spectral radiometer system, measures incoming light intensity and spectral distribution in different wavelength-bands. An additional data storage device allows recording of the measured data. The inclusive sensor system yields very high sensitivity to incoming light. Furthermore, outstanding linearity of the detector response over several orders of magnitude of incoming light is achieved. Additional benefits are ultra low power consumption and minimum size. The sensor system can be used in remote solar radiation monitoring applications like mobile solar power units as well as in long-term environmental monitoring systems where high precision and low power consumption is a necessity.

Abstract: A spectrometer includes a support having a bottom wall part in which a depression and a peripheral part are provided, and a side wall part, a light detection element supported by the side wall part while opposing the depression, and a dispersive part disposed on an inner surface of the depression. A length of the depression in a second direction in which a plurality of grating grooves included in the dispersive part is aligned is larger than a length of the depression in a third direction orthogonal to the second direction when viewed in a first direction in which the depression and the light detection element oppose each other. An area of the peripheral part adjacent to the depression in the second direction is larger than an area of the peripheral part adjacent to the depression in the third direction when viewed in the first direction.

Abstract: The invention relates to a multi-channel spectrometer device (10) for detecting/quantifying a predetermined analyte (5) in a medium (6). The device (10) comprises an input (11) for receiving radiation (7), a first plurality of optical modulators (12) adapted for transforming the radiation (7) in accordance with a first transfer function, and a second plurality of optical modulators (13) adapted for transforming the radiation (7) in accordance with a second transfer function. The spectrometer device also comprises a detector (15) for generating output signals (4) indicative for the intensity of each transformed radiation signal. The ratio of the number of optical modulators in the first plurality and the number of optical modulators in the second plurality is determined by the ratio of a reference spectrum of the predetermined analyte transformed by the first transfer function and the reference spectrum transformed by the second transfer function.

Abstract: A spectrometer comprises a plurality of isolated optical channels comprising a plurality of isolated optical paths. The isolated optical paths decrease cross-talk among the optical paths and allow the spectrometer to have a decreased length with increased resolution. In many embodiments, the isolated optical paths comprise isolated parallel optical paths that allow the length of the device to be decreased substantially. In many embodiments, each isolated optical path extends from a filter of a filter array, through a lens of a lens array, through a channel of a support array, to a region of a sensor array. Each region of the sensor array comprises a plurality of sensor elements in which a location of the sensor element corresponds to the wavelength of light received based on an angle of light received at the location, the focal length of the lens and the central wavelength of the filter.
