Abstract

We demonstrate a miniature broadband (13.3 MHz) fiber-tip photoacoustic probe with \pmb{\sim 68.32-\mu\mathrm{m}} thick MoS2-polydimethylsiloxane (PDMS) composite for accurate measurement of water and oil-water interface levels. The composite was applied to the tip of a double-clad fiber with an outer diameter of \pmb{125 \ \mu \mathrm{m}} using dip coating. The propagation time of an ultrasonic wave generated by a 5-ns pulsed laser excitation in liquids was extracted to determine water level or silicone oil-water interface in a glass tube. An excellent goodness of \pmb{\mathrm{fitt}(R{2}\approx 0.996)} was achieved with a high accuracy of \pmb{\sim 1.5\mu \mathrm{m}} in the tested water-level range of \pmb{0-2181\mu\mathrm{m}}. Then the proposed technique exhibited an average relative error of 0.68% for the oil-water interface detection, along with a good fitting coefficient of 98.7 ^% in the range of 0-8 mm. The presented photoacoustic probe therefore shows a great potential in compact accurate liquid level monitoring.
