    Abstract: Disclosed is a method for determining the reflectance of an object, the method including a step of solving an equation having several unknowns, the equation being obtained from formed images, the reflectance of the object and the illumination of the external light source being two unknowns of the equation. The step of solving the equation includes: calculating solution points of the equation, interpolating the calculated points by way of an interpolation function, and using at least one of the following approximations to solve the equation: a first approximation according to which each image is derived from the emission of a separate light flash, a second approximation according to which the interpolation function determines the stability points of the equation.

    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 system for the detection of components in a region of the atmosphere is disclosed, the system comprising a spectrometer assembly having a detector optically coupled to a optical assembly, the optical assembly receiving incident sunlight from the region of the atmosphere, the optical assembly having a field of view extending from the zenith to below the horizon; means for rotating the spectrometer assembly about a vertical axis; and a processor for receiving data from the spectrometer assembly and compiling data relating to the identity and concentration of components in the region of the atmosphere. A method of monitoring pollutants in a region of the atmosphere comprises providing a spectrometer assembly having a detector optically coupled to an optical assembly having a field of view extending from the zenith to below the horizon; exposing the spectrometer assembly to incident sunlight while rotating the spectrometer assembly about a substantially vertical axis; and processing signals received from the spectrometer assembly to analyse components in the atmosphere. The system and method are particularly useful in monitoring atmospheric pollutants arising from the combustion of hydrocarbon fuels, in particular oxides of nitrogen and/or sulphur. A preferred arrangement comprises a plurality of systems disposed at spaced apart locations and having their scanned regions overlapping.
