A photoacoustic sensing probe using optical fiber acoustic delay line

In this paper, we report a new photoacoustic sensing probe design consisting of two optical fibers. One optical fiber is used for delivering the excitation light pulses. The other one serves as an acoustic delay line to relay the generated PA signal from the target to an outside ultrasound transduce...

With the addition of suitable time delay, the original PA signal can be easily separated from the interference signals.

The testing results show that the PA sensing probe can provide good sensitivity and maintain high linearity over a wide range of concentrations.
