摘要 |
Electrically pulsed infrared radiation source made from a thin foil-shaped material, which may be operated as required with temperature amplitudes of 100 K or more at millisecond pulse lengths. The source may be manufactured from known materials, and may be mounted in a preferred design as a curve-shaped bridge between two fixtures. The radiation source is particularly well adapted to be used in connection with pulse based methods and sensors for identification, measurement and warning of gas occurrences by means of infrared radiation. Examples of such methods and sensors are included in the invention.
