Abstract
A system for identifying gases, the system having a plasma generator for generating a plasma using the gas to be identified and an array of detectors for detecting light emitted from the plasma. By analysing the output of the detectors, the gas can be identified. The system includes a plasma display (11) having two glass plates (36 and 38) patterned with strips that form the plasma electrodes. The intersection between the strips defines pixels which are individually addressable.
Claims14
A system for identifying gases, the system comprising means for forming a plasma using the gas to be identified, a sensor for sensing light emitted from the plasma and a processor adapted to use information on the sensed light to identify the gas.
A system as claimed in claim 3, comprising a memory for storing a spectra or data associated with a known gas, which spectra or data is used by the processor to identify the gas.
A system as claimed in any one of the preceding claims wherein the means for forming a plasma comprise electrodes.
A method of identifying gases, the method involving forming a plasma using the gas to be identified, sensing light emitted from the plasma and using the sensed light to identify the gas.
