Apparatus for detecting information on object

Abstract

An apparatus for detecting information on an object includes an irradiating unit, a detecting unit, and an information-obtaining unit. The irradiating unit irradiates the object with electromagnetic waves as a rectangular shaped beam. The electromagnetic waves include a frequency component in (or range of) at least part of a frequency region of 30 GHz to 30 THz, and have variations in magnitude at intervals of 10 −11 seconds or more or a temporally constant magnitude. The detecting unit detects the electromagnetic waves transmitted or reflected by the object through interaction therebetween. The information-obtaining unit obtains information on the object from information on the electromagnetic waves detected by the detecting unit.

1 . An apparatus for detecting information on an object, the apparatus comprising:
 an irradiating unit for irradiating the object with electromagnetic waves as a rectangular shaped beam, the electromagnetic waves comprising a frequency range of at least part of a frequency region of 30 GHz to 30 THz, and having variations in magnitude at intervals of 10 −11  seconds or more or a constant magnitude;   a detecting unit for detecting the electromagnetic waves transmitted or reflected by the object through interaction therebetween; and   an information-obtaining unit for obtaining information on the object from information on the electromagnetic waves detected by the detecting unit.
