TOMOGRAPHY DEVICE AND ELECTROMAGNETIC WAVE PULSE EMISSION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an electromagnetic wave pulse emission device and a tomography device capable of shortening the pulse width of electromagnetic wave pulse.SOLUTION: There is provided a device which performs processing so that two electromagnetic wave pulse portions applied to a sample have electric field intensity of mutually inverted polarities and a temporal difference between pulse peaks of the two electromagnetic wave pulse portions becomes a temporal difference within the time of the pulse width.
