Conventional photoacoustic (PA) systems use bulky high-power excitation laser sources and
ultrasonic transducers that need to be in contact with the sample, and hence have many
application limitations. In this paper, we present photoacoustic measurements using a small
silicon photonics-based Laser Doppler Vibrometer (LDV) and a compact pulsed laser diode.
The successful demonstration indicates that a compact and contactless PA system is possible.
