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 protective sheath having a closed end and an open end is sized to receive a hand held spectrometer. The spectrometer can be placed in the sheath to calibrate the spectrometer and to measure samples. In a calibration orientation, an optical head of the spectrometer can be oriented toward the closed end of the sheath where a calibration material is located. In a measurement orientation, the optical head of the spectrometer can be oriented toward the open end of the sheath in order to measure a sample. To change the orientation, the spectrometer can be removed from the sheath container and placed in the sheath container with the calibration orientation or the measurement orientation. Accessory container covers can be provided and placed on the open end of the sheath with samples placed therein in order to provide improved measurements.

Abstract: Snapshot spectral imagers comprise an imaging lens, a dispersed image sensor and a restricted isometry property (RIP) diffuser inserted in the optical path between the source image and the image sensor. The imagers are used to obtain a plurality of spectral images of the source object in different spectral bands in a single shot. In some embodiments, the RIP diffuser is one dimensional. An optional disperser may be added in the optical path, to provide further dispersion at the image sensor. In some embodiments, all imager components except the RIP diffuser may be part of a digital camera, with the RIP diffuser added externally. In some embodiments, the RIP diffuser may be included internally in a digital camera.

Abstract: Spectroscopic chemical analysis methods and apparatus are disclosed which employ deep ultraviolet (e.g. in the 200 nm to 300 nm spectral range) electron beam pumped wide bandgap semiconductor lasers, incoherent wide bandgap semiconductor light emitting devices, and hollow cathode metal ion lasers to perform non-contact, non-invasive detection of unknown chemical analytes. These deep ultraviolet sources enable dramatic size, weight and power consumption reductions of chemical analysis instruments. In some embodiments, Raman spectroscopic detection methods and apparatus use ultra-narrow-band angle tuning filters, acousto-optic tuning filters, and temperature tuned filters to enable ultra-miniature analyzers for chemical identification. In some embodiments Raman analysis is conducted along with photoluminescence spectroscopy (i.e. fluorescence and/or phosphorescence spectroscopy) to provide high levels of sensitivity and specificity in the same instrument.

Abstract: An observation apparatus (1) for enhancing the observation of an object (2) includes an output color image projector (8) for projecting a time sequence (31) of output color images (32) onto a projection area (40) on the object (2). The projector (8) has an output spectrum (60) including, at least in the visible-light range, a set of output spectral bands (60). The apparatus (1) further includes a multispectral camera system (4) for capturing a time sequence (21) of input color images (22) from the projection area (40) in at least two input spectral bands (42) different from the output spectral bands (62). The apparatus (1) is configured to derive the output color images (32) from the input color images (22) and project the output color images (32) onto the projection area (40) in real time. Because the input spectral bands differ from the output spectral bands, the output color images (32) can be processed to deviate arbitrarily from the input color images (22) without impacting operation of the camera system (4).

Abstract: A device images radiation from a scene. The scene can include two materials with spectral characteristics in different radiation wavelength regions. A static filtering arrangement includes two filters with different passbands corresponding to the two wavelength regions. An image forming optic forms an image of the scene on a detector. The radiation from the scene is imaged simultaneously through an f-number of less than 1.5 onto two detector pixel subsets. The imaged radiation on one pixel subset includes radiation in one wavelength region. The imaged radiation on the other pixel subset includes radiation in the other wavelength region. Electronic circuitry produces a pixel signal from each detector pixel. The pixel signals include information associated with absorption or emission of radiation in one of the respective wavelength regions by the two materials. The electronic circuitry determines the presence or absence of each of the two materials based on the pixel signals.

Abstract: A problem addressed by the present invention is to reduce the influence of stray light incident on each light-receiving element in the case of receiving each wavelength of light using a plurality of light-receiving elements. The multichannel spectrophotometer according to the present invention is a detector for simultaneously detecting the entirety of wavelength-dispersed light obtained by introducing light from a sample to a light-dispersing element (16) and dispersing this light into wavelengths by the light-dispersing element (16), including: a multichannel-type detector (17) including a plurality of light-receiving elements arranged in a one-dimensional form in a wavelength-dispersing direction of the light-dispersing element; a light amount calculator (221) for calculating the amount of light from a detection signal of each of the plurality of light-receiving elements (PD); a spectrum creator (222) for creating, from the amounts of light calculated by the light amount calculator (221), a spectrum showing a relationship between wavelength and the amount of light; and a computing section (224) for estimating, from the spectrum, the amount of stray light incident on each light-receiving element (PD) and correcting the spectrum by subtracting, from the amount of wavelength-dispersed light incident on each light-receiving element, the amount of stray light.

Abstract: A method for signal detection with a gas analysis system (1, 1′) includes a radiation source (3); a gas measuring section (9) containing gas to be measured; a Fabry-Perot interferometer (13); a thermal sensor (17) configured to cause a change in voltage between electrodes with electromagnetic radiation falling thereon and arranged such that radiation released by a second interferometer mirror falls on the thermal sensor. The method includes irradiating the gas measuring section with radiation source radiation, continuously increasing or decreasing a distance of interferometer mirrors during a generating of time signal pulses at a constant period of time from one another. After a predefined number of time signal pulses, the voltage generated between the electrodes is detected and stored as a measured signal value. After a further predefined number of time signal pulses, the voltage generated between the electrodes is detected again and stored as a measured signal value.

Abstract: A spectroscopic module 1 is provided with a spectroscopic unit 8 and a photodetector 9 in addition to a spectroscopic unit 7 and a photodetector 4 and thus can enhance its detection sensitivity for light in a wide wavelength range or different wavelength regions of light. A light-transmitting hole 4b is disposed between light detecting portions 4a, 9a, while a reflection unit 6 is provided so as to oppose a region R in a light-absorbing substrate 2, whereby the size can be kept from becoming larger. Ambient light La is absorbed by the region R in the substrate 2. Any part of the light La transmitted through the region R in the substrate 2 is reflected to the region R by the unit 6 formed so as to oppose the region R, whereby stray light can be inhibited from being caused by the incidence of the light La.
