OPTOACOUSTIC IMAGE PICK-UP SYSTEM AND OPTOACOUSTIC IMAGE PICK-UP DEVICE

摘要

In the present invention, an optoacoustic image pick-up system is provided with the following: an ultrasonic wave wave source (1) for projecting to a subject of image pick-up (4) ultrasonic waves formed by an acoustic signal having temporal waveforms that are repeated at a predetermined time interval; an acoustic lens (6) that is disposed so as to receive the scattered waves of ultrasonic waves (2) projected onto the subject of image pick-up (4) and that converts the scattered waves to plane waves; a translucent acoustic medium (8) provided in a region including a light axis (7) of the acoustic lens (6), the region being on the opposite side of the acoustic lens (6) from the subject of image pick-up (4); a light source (11) that emits single color light plane waves and that is disposed so that the advancing direction of the single color light plane waves and the light axis (7) of the acoustic lens (6) intersect at an angle other than 90 degrees and 180 degrees; an image forming lens (16) disposed so as to focus the diffraction light (201) of the single color light plane waves that was generated within the translucent acoustic medium (8); an image receiving unit (17) that acquires an optical image (18) formed by the image forming lens (16) as image information; and a distortion compensation unit (15) that corrects the distortion of the optical image (18) or the distortion of the image generated from the image information.
