Abstract

A detector unit of novel design is described which has been used successfully in model-chamber studies using visible light as a source of radiation, devised to find the geometric factors required for calculation of solid-to-solid radiant-heat-transfer problems. The detector unit may also be employed in investigations of interreflections in model rooms. Some of the useful properties of this detector unit are negligible cosine error, little fatigue, and linearity of response.
