1. , a kind of based on the light activated acousto-optic imaging method of pulse xenon lamp, it is characterized in that comprising the steps:

  • (1) the pulsed xenon fluorescent tube parallel after reflection output of pulsed light of sending;

    (2) pulsed light of parallel output through after optical filtering and converging, after perhaps directly converging, shines on the light absorption sample successively, and absorbent body luminous energy produces optoacoustic effect, sends ultrasound wave;

    (3) photoacoustic signal is gathered in ultrasonic detector fixed point scanning, rotation sweep or rectilinear scanning, by the acquisition component transmission and be stored in the computing machine;

    (4) signal is carried out filtering and integration after, rebuild light absorption by backprojection algorithm dorsad or linear projection'"'"'s algorithm and distribute and be shown in display screen.
