Abstract

In this work, we examine a system that exploits the photoacoustic effect to act as an ultrasonic pulse generator and an optical detector. At the core of the system are a solid substrate and an optical absorber. To test the performance as an ultrasonic generator, several substrate- absorber (SA) combinations are examined. The pulses generated by these systems are evaluated based on their bi- directional symmetry and characteristics of their Fourier spectra. To demonstrate the use of the SA system as an optical detector, a linearity study was performed for one specific choice of substrate and absorber. These substrate- absorber systems exhibit a variety of behaviors and form a versatile set of tools for ultrasound, optical and hybrid use.
