These methods are based on the measured data of infrared images on the target, which is irradiated by the high power millimeter-waves at several positions. The first and second moments and retrieved phase obtained from these data are used to determine the propagation direction of the millimeter-wave beam along the waveguide axis. It is demonstrated that these methods have sufficient resolution to discriminate 0.1 deg., which is required to restrict the transmission loss below 1% over the 100 GHz range.}, title = {Alignment Method of ECH Transmission Lines Based on the Moment and Phase Retrieval Method Using IR Images}, volume = {Vol. 81}, year = {2005} }
