“…On the acoustic signal detection side, the concave surface allows for wide angle signal reception. The sensitivity of the fiber hydrophone can be further enhanced by increasing the sensor Q factor, such as replacing the lossy metal mirrors with the low loss dielectric based distributed Bragg reflectors [21] , [30] or using other sensing method such as whispering gallery mode [32] , [33] , [34] . As shown in Fig.…”

“…According to the sensing principle, optical ultrasound sensors can be categorized into either resonance-based or nonresonance-based sensors. 29 , 31 Resonance-based sensors operate by detecting variations in a resonance cavity caused by the acoustic pressure. These variations subsequently manifest as changes in the intensity, phase, or wavelength of the probing light.…”

. Significance Photoacoustic (PA) imaging is an emerging biomedical imaging modality that can map optical absorption contrast in biological tissues by detecting ultrasound signal. Piezoelectric transducers are commonly used in PA imaging to detect the ultrasound signals. However, piezoelectric transducers suffer from low sensitivity when the dimensions are reduced and are easily influenced by electromagnetic interference. To avoid these limitations, various optical ultrasound sensors have been developed and shown their great potential in PA imaging. Aim Our study aims to summarize recent progress in optical ultrasound sensor technologies and their applications in PA imaging. Approach The commonly used optical ultrasound sensing techniques and their applications in PA systems are reviewed. The technical advances of different optical ultrasound sensors are summarized. Results Optical ultrasound sensors can provide wide bandwidth and improved sensitivity with miniatured size, which enables their applications in PA imaging. Conclusions The optical ultrasound sensors are promising transducers in PA imaging to provide higher-resolution images and can be used in new applications with their unique advantages.

“…Several materials have been proposed in previous works, including carbon nanotubes [ 15 , 16 ], carbon black [ 17 ], organic dyes [ 18 – 20 ], metallic nanoparticles [ 21 , 22 ], quantum dots [ 23 ], graphene [ 24 ] and candle soot [ 25 , 26 ]. For ultrasound reception, resonance-based acoustic sensors on the optical fibre tips are typically used to detect ultrasound reflections [ 27 ]. Among these sensors, plano-concave resonators with high detection sensitivity and broad detection bandwidth, which can detect the acoustically induced deformations of its polymer cavity, are well-suited for minimally invasive procedures [ 28 ].…”

All-optical ultrasound (OpUS) has emerged as an imaging paradigm well-suited to minimally invasive imaging due to its ability to provide high resolution imaging from miniaturised fibre optic devices. Here, we report a fibre optic device capable of concurrent laser interstitial thermal therapy (LITT) and real-time in situ all-optical ultrasound imaging for lesion monitoring. The device comprised three optical fibres: one each for ultrasound transmission, reception and thermal therapy light delivery. This device had a total lateral dimension of <1 mm and was integrated into a medical needle. Simultaneous LITT and monitoring were performed on ex vivo lamb kidney with lesion depth tracked using M-mode OpUS imaging. Using one set of laser energy parameters for LITT (5 W, 60 s), the lesion depth varied from 3.3 mm to 8.3 mm. In all cases, the full lesion depth could be visualised and measured with the OpUS images and there was a good statistical agreement with stereomicroscope images acquired after ablation (t=1.36, p=0.18). This work demonstrates the feasibility and potential of OpUS to guide LITT in tumour resection.
