Patent ID: 7683778

Claim:
An imaging apparatus comprising: an irradiating unit comprising: a generating unit for generating electromagnetic waves having a frequency range of at least part of a frequency region of 30 GHz to 30 THz; and a converting unit for converting an intensity distribution of the electromagnetic waves generated by the generating unit into a rectangular distribution; wherein the irradiating unit irradiates an object with the electromagnetic waves having the intensity distribution of the rectangular distribution; the imaging apparatus further comprising: an array detecting unit for detecting, by a plurality of pixels, the electromagnetic waves having the intensity distribution of the rectangular distribution and transmitted through or reflected by the object; an irradiated-position-changing unit for changing an irradiated position of the object that is irradiated with the electromagnetic waves having the intensity distribution of the rectangular distribution; and an image-obtaining unit for obtaining a plurality of images of the object corresponding to the rectangular distribution from the electromagnetic waves detected by the array detecting unit with the irradiated position being changed by the irradiated-position-changing unit, and for obtaining a whole image of the object from the plurality of images.
