In a radiation pyrometer a sharply focused real image of the source of the radiation to be measured is formed on a diaphragm through a small aperture in which a portion of the radiant energy passes to a radiation detector. With this arrangement the calibration of the instrument is independent of the distance from the source since variation of the energy from the source according to the inverse square-law is compensated by a variation in the proportion of energy in the real image which passes through the aperture due to the variation in area of the real image with variation in distance of the source. As shown in Fig. 1, a lens 1 forms a real image of the source of radiation on an operatured diaphragm 2 and a second lens 9 forms an image of the aperture, via a beam splitter 6 producing two beams 7 and 8 on photo-electric cells 10 and 11 respectively.

Infrared image pickup device

Method and apparatus for measuring temperature using infared techniques

Method and apparatus are provided for visibly outlining the energy zone to be measured by a radiometer. The method comprises the steps of providing a laser sighting device on the radiometer adapted to emit at least one laser beam against a surface whose temperature is to be measured and positioning said laser beam about the energy zone to visibly outline said energy zone. The apparatus comprises a laser sighting device adapted to emit at least one laser beam against the surface and means to position said laser beam about the energy zone to visibly outline said energy zone.

Optical fibre pyrometer - with mechanical switch for moving optical conductors in front of detector

A pyrometer consists of flexible optical fibres for conveying the radiation to a detector and a mechanical switch for moving each optical conductor in turn opposite the detector. Calibration of the pyrometer is easier since there is only one detector. The size of the pyrometer is also reduced. The pyrometer is esp. useful for observing the cooling of a continuously cast ingot.

APPARATUS FOR DETECTING OPTICAL RADIATION

LA PRESENTE INVENTION CONCERNE UN APPAREIL POUR LA DETECTION DE RAYONNEMENTS OPTIQUES COMPRENANT UNE TETE RECEPTRICE DE RAYONNEMENTS, UN GUIDE OPTIQUE DE CES RAYONNEMENTS POUR LES TRANSMETTRE A UN DISPOSITIF OPTIQUE DE DETECTION.
