Abstract
An ultrasonic measurement apparatus includes: a first phasing addition circuit that receives electric signals output from a plurality of reception ultrasonic elements, shifts the plurality of electric signals in a time axis direction to combine the plurality of electric signals, and outputs a composite signal; a second electro-optical conversion unit and a second light emitting unit that receive the composite signal, convert the composite signal into an optical signal, and output the optical signal; an optical cable through which the optical signal is transmitted; and a second light receiving unit and a second photoelectric conversion unit that receive the optical signal and converts the optical signal into an electric signal. The second light emitting unit outputs the optical signal after the first phasing addition circuit outputs the composite signal.
