Abstract
The temperature of a planar material (8) moving down a process path is measured by causing the material to pass through two openings (3,4) made in a waveguide (1) in such a way that the material effectively does not cut the electric field lines present on the walls of the guide (1) and also so the material (8) passes through the guide in a direction generally parallel to the electric field in the propagation mode of the waveguide and through a region of maximum field strength. The temperature of the planar material (8) is determined by measuring the thermal noise emitted by the material (8) as it passes through the slotted waveguide (1). The slots (3,4) for a rectangular waveguide operating in the TE.sub.10 mode are made along the centerline of the two broad sides of the guide.
