PURPOSE:To realize the transmission of supersonic in case of a large number of waves by delaying the operation of each vibrator element according to the cycle of the driving frequency and driving the vibrator element in the delayed timing according to the quantumized delayed time. CONSTITUTION:A pulser 2 and a preamplifier in a receiving system are connected with N-pieces of supersonic vibrator elements 1 (CH1-CHN), and trigger pulses are inputted into each pulser 2 from each trigger controller 3, and each supersonic vibrator element 1 is pulse-driven in the timing of the trigger pulse by the pulser 2, and performs oscillation, and transmits the supersonic wave. Into the trigger controller 3, the PRF signals, clock signals phi0-phi15, quantumized data MD0-MD5 for delayed time control, SD0-SD3, and wave quantity data W0, W7, etc., are transmitted from a main control circuit 4. The channel address sent out from the main control circuit 4 is sent into a decoder 5, and the LOAD signal is sent into the trigger controller 3 from the decoder 5, and the quantumized data for delayed time control and the wave quantity data are individually loaded. |
