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

Ultrasound detection is one of the major components of photoacoustic imaging systems.
Advancement in ultrasound transducer technology has a significant impact on the translation …

Objective: Photoacoustic (PA) imaging emerges as a unique tool to study biological samples
based on optical absorption contrast. In PA imaging, piezoelectric transducers are …

In photoacoustic imaging the ultrasonic signals are usually detected by contacting
transducers. For some applications contact with the tissue should be avoided. As …

We introduce all-optical photoacoustic projection imaging. An array of fiber-optic
interferometers is used to measure photoacoustic signals. The obtained images represent …

Speeding up the data acquisition is one of the central aims for advancing tomographic
imaging. On the one hand, this reduces motion artifacts due to undesired movements, and …

We present multimodal noncontact photoacoustic (PA) and optical coherence tomography
(OCT) imaging. PA signals are acquired remotely on the surface of a specimen with a Mach …

A fiber-optic interferometer is proposed and demonstrated experimentally for ultrasonic
detection. The sensor consists of a compact Michelson interferometer (MI), which is fixed in a …

In this work we present photoacoustic projection imaging with a 64-channel integrating line
detector array, which average the pressure over cylindrical surfaces. For imaging, the line …

We report on a novel imaging system for large depth of field photoacoustic scanning
macroscopy. Instead of commonly used piezoelectric transducers, fiber-optic based …
