1. rapid three-dimensional photoacoustic imaging method based on ultrasonic plane array detector is characterized in that comprising following operation steps:

  • (1) ultrasonic plane array detector is fixed on the surface of testee, is full of ultrasonic coupling liquid between ultrasonic plane array detector and testee;

    (2) carry out beam-shaping by the laser pulse that laser instrument sent by Space Optical System or fiber optic system after, make its forward direction uniform irradiation testee in detector, excite testee to produce photoacoustic signal;

    (3) each submatrix unit of ultrasonic plane array detector collects photoacoustic signal simultaneously, be converted into electric signal after, be stored in the computing machine by multi-channel parallel Acquisition Circuit transmission;

    (4) photoacoustic signal of gathering is handled, utilized three-dimensional phased reconstruction algorithm quick reconfiguration to go out the structural images of testee or the distribution situation of the interior different light absorption compositions of testee.
