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…
Increased SNR in acousto-optic imaging via coded ultrasound transmission
Ahiad Levi, Sagi Monin, Evgeny Hahamovich +3
Acousto-optic imaging (AOI) is a non-invasive method that uses acoustic modulation to map the light fluence inside biological tissue. In many AOI implementations, ultrasound pulses…
Ultrasound Detection Arrays Via Coded Hadamard Apertures
Evgeny Hahamovich, Amir Rosenthal
In the medical fields, ultrasound detection is often performed with piezoelectric arrays that enable one to simultaneously map the acoustic fields at several positions. In this wor…
Optoacoustic Model-Based Inversion Using Anisotropic Adaptive Total-Variation Regularization
Shai Biton, Nadav Arbel, Gilad Drozdov +2
In optoacoustic tomography, image reconstruction is often performed with incomplete or noisy data, leading to reconstruction errors. Significant improvement in reconstruction accur…
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…
