Method and device for measuring by radiometry micro - wavelength of the temperature of a plane at defilement, in particular a textile

摘要

The measurement of the temperature of the material in the plane 8 defilement is obtained by passing the material 8 through a waveguide 1 by two openings 3 and 4 applied of such a way that, on the one hand, they do not intersect in practice, the current lines presented on the walls of the guide 1, and secondly that the material 8 in the guide 1 has a general direction parallel to the electrical field in the mode of propagation of the guide 1 and passes through a maximum field zone, and by measuring the thermal noise issued by the material 8 for its stay in the slotted waveguide 1. / p & & p & in the case of a rectangular waveguide 1, operating according to the te mode, the two openings 3 and 4 are applied according to the median axis of the two large faces.
