    Abstract: A plurality of thermal images of an object each having been formed at a different time are displayed on a single screen of a television monitor (7) simply and economically. This is achieved by a thermal imaging apparatus consisting of: an infrared (IR) camera (1) to scan the object and to produce a detected video output; a TV monitor (7) to display the thermal images, and a hard memory (3) to convert the speed of the IR camera scan to the TV monitor display. Memory capacity is kept to a minimum in memorizing image data of one frame scan. The IR camera (1) scans so that the object is in a limited part of the field-of-view (FOV), the hard memory writes the resulting limited video signals into a limited part of the memory (3) corresponding to the limited part of the FOV at the scan speed. Each group of limited image data having been taken at a different time is stored. Then all image data groups stored in the memory (3) are read out at the TV displaying speed and displayed on the TV monitor (7) so that several thermal images can be observed together.

    Abstract: A flame quality analyser for analysing one or more properties of a flame from a burner comprises a fibre optic array (32,33) including a plurality of optical fibres each having a light-receiving end lying in a line and facing the flame. The line may extend parallel to the flame and burner axis (array 32) or may extend perpendicular to that axis (array 33). The light received by the fibre optic array (32,33) is provided as a sheet of light to a monochromator which spreads the light into its component wavelengths. A pair of spaced apart arrays of light detectors is then utilised to measure the light at two discrete wavelengths. This detection produces signals that can be analysed to generate temperature and particles distribution values for the flame across its length or width.

    Abstract: This invention relates to a novel fiber optic temperature sensor based on internally or self-generated thermal radiation. The wavelengths of the spectral composition of the self-generated thermal radiation vary along the length of an optical fiber as a function of the variations in the temperature of an object along the length of the optical fiber. However, since the total radiation varies exponentially with temperature, the spectral composition .and total power of the radiation transmitted to an end of the optical fiber is determined substantially by the highest temperature region along the optical fiber whereby the temperature, location and length of a hot spot, or region, of the object is determined.

    Abstract: An apparatus and method for remotely measuring emissivity and hence temperature of a surface of an object are disclosed. The apparatus includes a detector having a radiation receptor (14) for measuring infra-red radiation, an integrating cavity (10) surrounding the receptor for receiving radiation from a surface (23) facing the cavity and delivering the radiation to the receptor, at least two sources of infra-red containing radiation (15, 16) (e.g. light from an incandescent lamp) within the integrating cavity positioned to produce separate beams (5, 5') of the radiation which strike the surface at different angles suitable for reflection to the receptor, and a processor (18) for determining the temperature of the surface from the radiation measured by the detecting means. The infra-red containing radiation is preferably modulated to cause an on/off fluctuation of the intensity of the radiation so that the component of the signal from the detector resulting from reflected radiation can be distinguished from the component due to radiation emitted from the surface due to its temperature. The radiation is preferably measured at two different wavelengths so that a ratio technique may be employed. The use of at least two mutually angled radiation beams compensates for anisotropy of the surface whose temperature is to be measured.
