Abstract: This invention relates to a method of and system for facilitating detection of a particular predetermined gas in a scene (14) under observation. The gas in the scene is typically associated with a gas leak in equipment. To this end, the system comprises an infrared camera arrangement (12); a strobing illuminator device (22) having a strobing frequency matched to a frame rate of the camera; and a processing arrangement (24). The processing arrangement is configured to store a prior frame obtained via the infrared camera arrangement; and compare a current frame with the stored prior frame and generate an output signal in response to said comparison. The system also comprises a display device (26) configured to display an output image based at least on the output signal generated by the processing arrangement so as to facilitate detection of the particular predetermined gas, in use.

Abstract: An index value is calculated for rating an eyeglass (1) with respect to protection against UV hazard. Said index value is based on integrated UV transmission value through the eyeglass (1) and integrated UV reflection value related to a back face (lb) of the eyeglass (1). Thus, the index value takes into account actual wearing conditions where UV eye exposure is due either to transmission (T) through the eyeglass (1) or reflection (R) on the eyeglass (1) back face (lb). Respective index values obtained for a set of eyeglasses (1) allow easy sorting of the eyeglasses with respect to UV protection efficiency.

Abstract: A reflectivity absorption system for identifying a target precious or semi-precious material can include a detector, a filter system, and an output display. The detector system is capable of detecting a reflected electromagnetic radiation at a primary wavelength and a secondary wavelength. The reflected electromagnetic radiation can be produced from sunlight or other light source. The primary wavelength corresponds to an upper reflectivity of the target material while the secondary wavelength corresponds to a lower reflectivity of the target material. Reflectivity is a function of wavelength such that identifiable variations in wavelength can be observed for certain materials over specific wavelength ranges which are then compared to a known standard reflectivity response for the indicated wavelengths. These systems can be used in portable, handheld, or stationary configurations and can identify exposed target materials in real-time.

Abstract: A method and a system are provided for calculating the spectral absorbance using sunlight. With this method, methane (CH4) in open air can be detected using NIR spectrometers. It does not require any laser illumination of methane molecules in an outdoor environment. Instead, sunlight is used as the light source. This system works from early morning to late evening under various weather conditions (sunny, partly cloudy, cloudy, windy, etc.). Although theoretical background and experimental procedure for methane (CH4) absorbance is disclosed, the entire method can be applied to any other species as well when the wavelength range of interest overlaps with sunlight spectra.

Abstract: The sun's energy is used in combination of movable and fixed diffuser plates, windows and apertures which are positioned in a series of test sequences (modes) for reflectance monitoring and calibration without the use of man-made sources. There are three embodiments, or implementations, of the invention--one embodiment uses two diffusers--a working diffuser and a secondary diffuser--the second embodiment uses three diffusers, a working diffuser, a secondary diffuser and a reference diffuser--and the third embodiment uses two diffusers--a working diffuser and a secondary diffuser, the latter also functioning as a cover for the working diffuser. The movable diffusers are mounted on rotatable cones and, in all embodiments, the sun is blocked from reaching the diffusers when not in use. Thus, the sun is used as a stable source for calibration and monitoring and the sun/diffuser combination is used in such a way that the response of all elements of the optical subsystem of the TOMS can be unambiguously and efficiently characterized with high accuracy and precision.

Abstract: A method and apparatus for determining the presence, location and relative concentration of certain fluorescent materials in a scene that is illuminated by sunlight. The particular fluorescent materials are characterized in that they fluoresce at wavelengths coincident with one or more Fraunhofer absorption bands. Two images are formed from light collected from the scene. One of the images consists mainly of light from the scene having a spectral band-pass inside a Fraunhofer absorption band and the other image consists mainly of light from the scene having a spectral bandpass in the continuum near the same Fraunhofer absorption band. The two images are normalized so that intensities on corresponding portions of each image due to reflected solar radiation are equal. The ''''continuum'''' image is then subtracted from the ''''Fraunhofer'''' image. The resulting difference image consists primarily of fluorescent radiation derived from the fluorescent materials or objects in the scene and provides a direct visual indication of their presence, location and relative concentration.

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.
