Design and simulation of compact portable photoacoustic driver circuit

Photoacoustic spectroscopy is a versatile spectroscopic hybrid technique that combines optics and ultrasound. Requiring powerful short pulses, solid-state lasers are often employed which has proven a barrier for widespread clinical photoacoustic applications due to size, cost, and safety constraints. We are proposing a compact portable photoacoustic driver circuit including on board power regulation and capable of generating nanosecond high current pulses to overdrive LEDs or laser diodes, opening the possibility for continuous monitoring and point of care applications.
