PROBLEM TO BE SOLVED: To reduce a load of a mechanical mechanism for scanning, and to focus easily, in an imaging device for performing imaging by measuring with a sensor constituted of an antenna or an amplifier, a millimeter wave radiated or reflected from an object.SOLUTION: An imaging unit 120 images a subject image (millimeter wave image) picked up by a dielectric lens 110. The imaging unit 120 has a rotating object 121, and a plurality of sensors 124 are arranged on the surface of rotation of the rotating object 121. Each sensor 124 is constituted of the antenna for acquiring the millimeter wave, the amplifier for amplifying an output signal from the antenna or the like. The plurality of sensors 124 scan the subject image following rotation of the rotating object 121, measure the millimeter wave at each part of the subject image, and output a signal corresponding to a measured value. The rotating object 121 is moved in the optical axis direction of the dielectric lens 110 by a moving mechanism 141, and focusing is performed, to thereby acquire a plurality of focused images. |
