Abstract: A radiation measuring device for measuring electromagnetic radiation originating from an external source. The radiation measuring device includes, a spectrometer, a pyranometer, a pyrgeometer, a diffuser, and a control unit. The spectrometer and a pyranometer are positioned in a sensor zone of a housing of the radiation measuring device. The spectrometer measures visible shortwave radiation and near-infrared shortwave radiation received at the sensor zone. The pyranometer measures shortwave radiation received at the sensor zone. The pyrgeometer is positioned in another sensor zone of the housing and measures longwave radiation received at the other sensor zone. The control unit receives radiation measurements from the spectrometer, pyranometer, and pyrgeometer. A corrected amount of radiation received at the sensor zones of the radiation measuring device is determined from the received radiation measurements. Other embodiments are described and claimed.

Abstract: The present invention is a spectroscopic analyzer that when measuring the concentration of a predetermined component contained in sample gas in a reduced pressure state lower than atmospheric pressure, obtains the concentration of the predetermined component with accuracy. The spectroscopic analyzer is one that measures the absorbance of the predetermined component contained in the sample gas in a reduced pressure state lower than atmospheric pressure, and calculates the concentration of the predetermined component with use of a calibration curve indicating the relationship between the absorbance of the predetermined component and the concentration of the predetermined component and a relational expression between the pressure of the sample gas at the time of the measurement and the concentration of the predetermined component. In addition, in a graph with one axis as pressure axis and the other axis as concentration axis, the relational expression has an intersection point other than zero with the pressure axis.

Abstract: A filter for removing coherent radiation from a source in a field of view, substantially independent of the size of the source, comprises a first reticle 22 located in the path of received light 21, a first lens 23 producing an optical transform of the first reticle 22 at a second reticle 24 located in the image plane of the first lens 23, a second lens 25 producing an optical transform of the second reticle 24 and a third reticle 26 located in the image plane of the second lens 25. The arrangement is such that the spatial transmittance of the third reticle 26 is selected to block at least part of the diffracted image of the first reticle 22 produced in the image plane of the second lens 25 and characteristic of the coherent radiation. Preferably the optical transforms are Fourier Transforms. A monochromatic coherent source in the field of view produces a pattern of diffracted energy in the image plane of the second lens which is independent of the size of the source. Thus, by providing a suitable reticle 26 in the image plane of the second lens light from a coherent source in the field of view can be blocked while polychromatic light is transmitted. The first and second reticles may be periodic picket-fence reticles or different spatial frequencies may be used for the first and third reticles so as to vary the stop-band characteristics of the filter.

Abstract: A method and apparatus for obtaining reference samples during the generation of a mid-infrared (MW) image without requiring that the sample being imaged be removed is disclosed. A tunable MIR laser generates a light beam that is focused onto a specimen on a specimen stage that moves the specimen in a first direction. An optical assembly includes a scanning assembly having a focusing lens and a mirror that moves in a second direction, different from the first direction, relative to the stage such that the focusing lens maintains a fixed distance between the focusing lens and the specimen stage. A light detector measures an intensity of light leaving the point on the specimen. A controller forms an image from the measured intensity. A reference stage is positioned such that the mirror moves over the reference stage in response to a command so that the controller can also make a reference measurement.

Abstract: Various embodiments include systems and methods to provide selectable variable gain to signals in measurements using incident radiation. The selectable variable gain may be used to normalize signals modulated in measurements using incident radiation. The selectable variable gain may be attained using a number of different techniques or various combinations of these techniques. These techniques may include modulating a modulator having modulating elements in which at least one modulating element acts on incident radiation differently from another modulating element of the modulator, modulating the use of electronic components in electronic circuitry of a detector, modulating a source of radiation or combinations thereof. Additional apparatus, systems, and methods are disclosed.

Abstract: Various embodiments disclosed herein describe a divided-aperture infrared spectral imaging (DAISI) system that is adapted to acquire multiple IR images of a scene with a single-shot (also referred to as a snapshot). The plurality of acquired images having different wavelength compositions that are obtained generally simultaneously. The system includes at least two optical channels that are spatially and spectrally different from one another. Each of the at least two optical channels are configured to transfer IR radiation incident on the optical system towards an optical FPA unit comprising at least two detector arrays disposed in the focal plane of two corresponding focusing lenses. The system further comprises at least one temperature reference source or surface that is used to dynamically calibrate the two detector arrays and compensate for a temperature difference between the two detector arrays.

Abstract: A method for determining spectral calibration data (λcal(Sd), Sd,cal(λ)) of a Fabry-Perot interferometer (100) comprises: forming a plurality of filtered spectral peaks (P′1, P′2) by filtering input light (LB1) with a Fabry-Perot etalon (50) such that a first filtered peak (P′1) corresponds to a first transmittance peak (P1) of the etalon (50), and such that a second filtered peak (P′2) corresponds to a second transmittance peak (P1) of the etalon (50), using the Fabry-Perot interferometer (100) for measuring a spectral intensity distribution (M(Sd)) of the filtered spectral peaks (P′1, P′2), wherein the spectral intensity distribution (M(Sd)) is measured by varying the mirror gap (dFP) of the Fabry-Perot interferometer (100), and by providing a control signal (Sd) indicative of the mirror gap (dFP), and determining the spectral calibration data (λcal(Sd), Sd,cal(λ)) by matching the measured spectral intensity distribution (M(Sd)) with the spectral transmittance (TE(λ)) of the etalon (50).

Abstract: Described are a shutter assembly, a spectrometer, and a method for calibrating a spectrometer. For example, the method may include positioning a shutter including a mirror into a first position in an illumination path of an excitation light beam such that a measurement window is blocked. The mirror may be operable to direct at least one of: (1) the illumination path to a spectral calibration material, (2) a first collection path extending from the spectral calibration material, and (3) a second collection path of a spectral calibration light beam. The method may include directing a returned light from the receiving optics unit to an imaging device; processing the returned light at the imaging device into one or more image signals; analyzing and comparing the image signals with approved image signals; and providing an indication of whether the comparative results of the analysis are within acceptable tolerances.
