This report presents what the author have done for the Final Year Project. Firstly, involved the design of a palm size laser diode driver circuit board which later on could be used in the photoacoustic imaging system for driving a low power laser diode. Electrical circuit design, circuit simulation on LTSpice, PCB layout design and hands on experiments were also performed. Secondly, studied the photoacoustic effect and furthermore a photoacoustic imaging system was implemented to achieve high spatial resolution and good contrast image. Last but not least, had a basic understanding of photoacoustic effects, coupled with the research study on PA-SAW devices, a PA-SAW based particle sensing system was designed to effective enhance the sensing signal.
