Abstract
An ultrasonic probe which does not require electric wiring to a large number of microcomponents and does not induce increase of crosstalk and electric impedance. This ultrasonic probe comprises an optical transmission path array incorporating a plurality of optical transmission paths on which light is incident at first ends thereof; and a plurality of ultrasonic detecting elements which are formed on these optical transmission at the second ends thereof and adapted to reflect the light incident through the respective fibers based on ultrasonic waves applied thereon.
Claims30
An ultrasonic probe comprising:
- an optical transmission path array including a plurality of optical transmission paths on which light is incident at first ends thereof;
- and
- a plurality of ultrasonic detecting elements formed at second ends of said plurality of optical transmission paths, for modulating light incident through the respective transmission paths on the basis of an applied ultrasonic wave.
An ultrasonic receiver comprising:
- a plurality of ultrasonic detecting elements, arrayed in a two-dimensional arrangement, for modulating light on the basis of an applied ultrasonic wave;
- and
- a photodetector for detecting light output from said plurality of ultrasonic detecting elements.
An ultrasonic diagnostic apparatus comprising:
- a drive signal generating circuit for generating a drive signal for transmitting ultrasonic waves;
- an ultrasonic transmission unit for directing ultrasonic waves onto an object in response to the drive signal supplied from said drive signal generating circuit;
- an ultrasonic detection unit including a plurality of ultrasonic detecting elements for modulating light based on an applied ultrasonic wave;
- a photodetector for detecting the light output from said ultrasonic detection unit to generate a detection signal;
- signal processing means for processing the detection signal supplied from said photodetector;
- and
- control means for controlling transmission timing of said drive signal generating circuit and receives timing of said signal processing means.
