Abstract

PURPOSE:To perform detection over a wide range in a short time by arraying ultrasonic wave vibrators so as to have directional beams and scanning the directional beams at the same time. CONSTITUTION:The ultrasonic wave vibrators S1-S5 which send ultrasonic waves and receives their reflected waves are arrayed on the same plane at equal intervals to constitute the ultrasonic array. Then the intervals of the vibrators S1-S5 are 1.4lambda (lambda: wavelength of ultrasonic wave), so three directional beams are generated. Assuming that those three directional beams are in directions of angles phi1, phi3, and phi5, delay circuits D1-D5 deviate the directions of the directional beams by an angle phi to angles phi2, phi4, phi6 respectively and then detection is performed over a wide range from phi1-phi6 by one scan.
