Abstract:
1. An object information acquisition apparatus for acquiring information on the inside of an object, the apparatus comprising: an electromagnetic wave generation unit capable of outputting an electromagnetic wave containing a frequency component of part of the frequency range between 30 GHz and 30 THz and of changing an output intensity of the electromagnetic wave; an irradiation unit that irradiates the electromagnetic wave to the object; a scanning unit that changes the relative position of the irradiated electromagnetic wave and the object; and a detection unit that detects the electromagnetic wave transmitted through or reflected by the object as a result of interaction of the object and the electromagnetic wave, the apparatus being adapted to acquire tomographic information of planes of different levels in the inside of the object relative to the direction of depth thereof in the region of the object of information acquisition according to a signal detected by the detection unit by combining the operation of changing the relative position by the scanning unit and the operation of changing the intensity of the electromagnetic wave by the electromagnetic wave generation unit.
