Abstract

PURPOSE: To improve resolution of the direction and depth of a sound and change informations about the distributional state on the sound source into pictures by detecting radiations from a matter on a semi-spherical surface.
CONSTITUTION: On a semi-sphere encircling a radiator 11 of irregular sonic wave are arranged receivers 1aW1n. Signals from a fixed receiver 1k and signals from a plurarity of receivers 1aWn which have spacially different locations are received, signals from movable wave receivers are selected one after another and the A/D conversion 7 of each signal is carried out keeping simultaneity with signals of the location-fixed wave receiver. Self-spectrum of the fixed wave receiver and mutual spectrum with selective signals of the movable wave receivers are counted in regard to sets of various orders and frequencies, hologram signals are produced and memorized 8. Images on each point within the specified range on the voluntarily specified section of a 3-dimensional sound source distribution about the memory signals is regenerated and displayed 9 as a 2-dimensional sectional image by means of calculation of counter propagation of wave motion.
