Abstract: The invention relates generally to the field of substance and material detection, inspection, and classification at wavelengths between approximately 200 nm and approximately 1800 nm. In particular, a handheld Enhanced Photoemission Spectroscopy ('EPS') detection system with a high degree of specificity and accuracy, capable of use at small and substantial standoff distances (e.g., greater than 12 inches) is utilized to identify specific substances (e.g., controlled substances, illegal drugs and explosives, and other substances of which trace detection would be of benefit) and mixtures thereof in order to provide information to officials for identification purposes and assists in determinations related to the legality, hazardous nature and/or disposition decision of such substance(s).

Abstract: An improved light-emitting panel having a plurality of micro-components (40) at least partially disposed in a socket(30) and sandwiched between two substrates (10, 20) is disclosed. Each micro-component (40) contains a gas or gas-mixture capable of ionization when a sufficiently large voltage is supplied across the micro-component via at least two electrodes.

Abstract: Vacuum ultraviolet radiation detection apparatus (10) comprises a radiation detector (30) in a chamber (12). The detector (30) receives ultraviolet radiation from a radiation source (36). The chamber is evacuated using a dry vacuum pump (18) to a relatively poor vacuum of no less than 5 Pa. UV transparent gas is supplied from a gas supply (26), into the chamber (12) at a relatively low flow rate (around 0.1 litres/minute) so as to provide an overall pressure in the chamber (12) of between 100 and 1,000 Pa. The use of a relatively inexpensive pump coupled with a lower gas flow rate provides significant cost savings.

Abstract: The invention relates to a method and a device for carrying out emission spectroscopy, in particular laser emission spectroscopy. According to said method, a pulsed laser beam is automatically focussed on a workpiece to generate a laser-induced plasma, the radiation emitted from the plasma is detected and an elemental analysis is performed using the captured radiation spectrum. The invention is characterised in that a laser beam impingement is carried out with a variable pulse interval DELTA T, that prior to the plasma generation, additional geometric parameters P 1, P 2 .. PN of a potential measurement location on the workpiece surface, in addition to the distance d of the autofocus lens from said workpiece surface are determined and in that an elemental analysis is only performed for the potential measurement locations, at which at least one of the additional geometric parameters lies within a predefined tolerance range [T1..T2].

Abstract: This invention presents a spectroscopic analyzing apparatus, which can increase the SN ratio, by executing an optimal spectroscopic analysis of light from a light source, which gives different light spectrum inherent to the component to be measured and has a different strength distribution according to the light emitting position therein, for example, light emitted from ICP. This invention comprises a light source (2), which emits different light spectra, each light spectrum being inherent to a component to be measured and having a different strength distribution according to the respective light emitting position; a spectroscope (6) for dispersing the light from the light source (2) according to its wavelength; at least one CTD photo sensor (8a - 8c) for sensing light being dispersed by the spectroscope (6) and lying within a specific wavelength range; and an optical system(9) for analyzing the light sensed by said at least one CTD photo sensor (8a - 8c), thereby making an image of the light source (2).
