1. An imaging method comprising:

  • receiving a first light beam from a light source;

    splitting the first light beam into a plurality of second light beams using a beam-divider;

    focusing the plurality of second light beams on a respective plurality of locations in an object of interest using a focusing device, the plurality of second light beams causing the object of interest to emit time-resolved acoustic signals from the respective plurality of locations; and

    receiving the time-resolved acoustic signals from the respective plurality of locations in the object of interest using an ultrasonic transducer array, the respective plurality of locations positioned within a field of view of the ultrasonic transducer array;

    wherein the imaging method is an optical-resolution photoacoustic imaging method with a lateral resolution of 10 μ

    m or less.
