NONDESTRUCTIVE EVALUATION APPARATUS AND MICROWAVE IRRADIATION APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a nondestructive evaluation apparatus and a microwave irradiation apparatus easily configured before measurement.;SOLUTION: The nondestructive evaluation apparatus 100 has dielectric lenses 31, 32 as convex lenses for deflecting a traveling direction of an entering microwave according to a permittivity difference between an atmosphere and emitting the microwave. The microwave oscillated (generated) by a microwave controller 10 and emitted (transmitted) from a horn antenna 20 through a cable 11 passes through the dielectric lens 31 and has the parallel traveling direction. The collimated microwave is converged by passing through the dielectric lens 32 and focused in a determined focal length. The microwave emitted to a subject 40 placed at the location and reflected by the subject returns to the horn antenna 20 in the backward traveling direction and is received by the microwave controller 10 through the cable 11.;COPYRIGHT: (C)2004,JPO
