Abstract:
A phase computing device according to an embodiment of the present technology includes a coordinate determination unit and a computing unit.
The coordinate determination unit determines space coordinates at which an interference pattern of wave motion emitted from a vibrator phased array is to be presented, the wave motion including ultrasonic waves, electromagnetic waves, or other waves. The computing unit calculates an initial phase of each vibrator, a sum of energy densities of the wave motion at respective points of the space coordinates being maximum in the initial phase.
