Paper Abstract

In this paper, a novel method for photoacoustic (PA) waves to imaging is proposed. A focused probe ultrasonic beam passes through a specimen and tags the position of the interested PA signal. Reconstruction of the original PA signal in situ is accomplished by demodulating the probe-beam. The method provides new measurement system with to improve signal-to-noise ratio and to take out more original messages. Applied the proper impulse of the detector and filter-back-project algorithm, a 2D PA tomograph was obtained.
