The invention relates to a device for producing and detecting induced heat radiation, in which movable mirror components (3, 6) are moved into and out of a crossed beam path (23) across a stepping motor (8) so as to be isogonal in the beam path (23).

Pyrometric determination of radiance and/ or temperature

A method for determining the radiance and/ or temperature of a rotating object such as a turbine blade B comprises determining the reflectivity of the object B under low-temperature conditions where the object is non-emissive, the radiance of the blade under high temperature conditions and measuring the intensity of incident radiation from external sources such as a combustor C.

A minimum-picking process may be used on the resulting data to reduce the effects of flare. The apparatus may comprise a retractable probe P which rotates about an axis A1. The incident radiation and the radiance of the object may be monitored by two separate detectors D2, D1, or alternatively, by a common pyrometer system (figure 2).

In a radiation pyrometer in a gas turbine engine, non-uniformly distributed changes in transparency of an optical element in the system, e.g. contamination of pyrometer objective lens L1 by combustion products from the turbine can be automatically detected. Lens L1 focusses radiation from target T onto an additional lens L2, which in turn focusses it onto the end E of the fibre-optic bundle F. Considered reciprocally, lens L2 images the end E of fibre-optic F into L1, so that although each optical fibre in end E receives radiation from all parts of target T, each fibre is imaged into a corresponding discrete area of L1. Fibre-optic bundle F comprises two (or more) sub-bundles F1 and F2 forming complementary sub-areas of end E and each sub-bundle is provided with its own photodetector P1, P2 and associated pre-amplifier A1,A2 adjusted so that their outputs A1S1 and A2,S2 are matched at the non-contamination condition.
