Abstract
Provided are an electromagnetic wave wavefront shaping element, an electromagnetic wave imaging device using the same, and a method of electromagnetic wave imaging for performing a high-speed imaging with electromagnetic wave. An electromagnetic wave wavefront shaping element (1) which shapes the wavefront of an electromagnetic wave (10), comprising: a semiconductor (23); an insulator (22) formed on the semiconductor (23); a plurality of electrodes (21) which are arrayed on the insulator (22); a voltage applying means (3) which applies given voltages between the plurality of electrodes (21) and the semiconductor (23) respectively and controls the applied voltages respectively; wherein when a pulse laser (9) is incident onto the semiconductor (23), the emitting intensity of the electromagnetic wave (10) which is generated from the pulse laser incident surface (23a) of the semiconductor (23) corresponding to the electrode (21) to which the voltage is applied, is controlled by controlling the applied voltages with the voltage applying means (3) respectively.
