Homodyne Time-Domain Acousto-Optic Imaging for Low-Gain Photodetectors
Ahiad Refael Levi, Yoav Hazan, Aner Lev +2
Acousto-optics imaging (AOI) is a hybrid imaging modality that is capable of mapping the light fluence rate in deep tissue by local ultrasound modulation of the diffused photons. S…

Phase modulated pulse interferometry for simultaneous multi-channel ultrasound detection
Yoav Hazan, Amir Rosenthal
In optical detection of ultrasound, resonators with high Q-factors are often used to maximize sensitivity. However, in order to perform parallel interrogation, conventional interfe…

Enhanced sensitivity of silicon-photonics-based ultrasound detection via BCB coating
Resmi Ravi Kumar, Evgeny Hahamovich, Shai Tsesses +3
Ultrasound detection via silicon waveguides relies on the ability of acoustic waves to modulate the effective refractive index of the guided modes. However, the low photo-elastic r…
