Originally developed for diagnostic ultrasound imaging, piezoelectric transducers are the
most widespread technology employed in optoacoustic (photoacoustic) signal detection …

A miniature forward-viewing endoscopic probe that provides high-resolution 3D
photoacoustic images is demonstrated. The probe is of outer diameter 3.2 mm and …

Endoscopic imaging is the main method for detecting gastrointestinal diseases, which
adversely affect human health. White light endoscopy (WLE) was the first method used for …

Significance: Acoustically detecting the rich optical absorption contrast in biological tissues,
photoacoustic tomography (PAT) seamlessly bridges the functional and molecular sensitivity …

An optical fiber based Fabry-Pérot interferometer whose resonant wavelength can be
dynamically tuned was designed and realized for photoacoustic mesoscopy. The optical …

Optical ultrasound sensors have been increasingly employed in biomedical diagnosis and
photoacoustic imaging (PAI) due to high sensitivity and resolution. PAI could visualize the …

We experimentally demonstrated and quantitatively evaluated a non-contact nanometer-
displacement measurement using phase-diversity optical digital coherent detection …

Cutting-edge biomedical ultrasound imaging demands advanced ultrasound sensing
capabilities such as broad bandwidth, high sensitivity, and parallel sensing. A variety of …

A miniature all-optical ultrasound imaging system is presented that generates three-
dimensional images using a stationary, real acoustic source aperture. Discrete acoustic …

Backgrounds Photoacoustic endoscopic (PAE) imaging is a rapidly emerging interventional
imaging modality for identification and characterization of intraluminal pathological tissues …
