Tomography apparatus and electromagnetic pulse transmitting apparatus

摘要

To provide an electromagnetic pulse transmitting apparatus and a tomography apparatus capable of shortening an electromagnetic pulse. The apparatus performs processing such that two electromagnetic pulse portions emitted to an object have an electric field intensity of mutually opposite polarity and the time difference between pulse peaks of the two electromagnetic pulse portions is a time difference within a time of a pulse width.

1. A tomography apparatus comprising:
a light source that generates an electromagnetic pulse; a detection section that detects the electromagnetic pulse; an optical system that guides the electromagnetic pulse to the detection section; a processing section that calculates a time waveform of the electromagnetic pulse from a signal transmitted from the detection section; and an electromagnetic pulse shaping section which is provided in an optical path of the electromagnetic pulse from the light source to the detection section, and which divides the electromagnetic pulse into a plurality of electromagnetic pulse portions in such a manner that when transmitted from the electromagnetic pulse shaping section, the electromagnetic pulse portions have electric field intensities of mutually opposite polarities and have a time difference within a time of a pulse width which is a full width at half maximum of the electric field intensities of the electromagnetic pulse.
