Golay cell

A thermal radiation detector consisting of a small cell with a blackened plastic front face that bulges slightly when heat is received by it. The bulging tilts a small mirror, which, in turn, varies the amount of light proceeding from a lamp to a photocell. The radiation is measured by sensing the increase in pressure in a gas chamber as the temperature rises when radiation is absorbed.
