High frequency optoacoustic microscopy
2009 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2009Photoacoustic imaging--also called optoacoustic imaging--is a new hybrid modality of high tissue contrast which is based on the varying optical properties of tissue. The acoustic signal generated by pulsed laser absorption reports tissue-specific information with high spatial resolution. To increase the intrinsic contrast in tissue, absorbing particles

Linear optoacoustic underwater communication
Applied Optics, 2005The linear mechanism for optical-to-acoustic energy conversion is explored for optoacoustic communication from an in-air platform or surface vessel to a submerged vessel such as a submarine or unmanned undersea vehicle. The communication range that can be achieved is addressed.

The optical imaging techniques available for clinical skin imaging are fundamentally limited in their depth scope to a few hundred microns and face difficulties in their functional and molecular imaging capabilities. Furthermore, histopathological analysis is still the only method of choice to accurately diagnose several skin diseases.

Contemporary Physics, 1979
Abstract The generation of acoustic signals following optical absorption in gases and solids is described. Important parameters in the design of cells and their relationships to detection sensitivity and limiting noise signals are discussed. Examples are given of important applications of the optoacoustic effect in pollution monitoring, the measurement

Imaging modalities play an increasing role in today's medical diagnostics. Among them, ultrasound (US) is one the most widespread techniques although it has relatively poor soft tissue contrast. Furthermore, US is poorly suited as a modality for molecular imaging (MI).Methods such as Doppler and contrast-enhanced US (CEUS) allow functional imaging of ...

Optimal optoacoustic detector design
Applied Optics, 1975Optoacoustic detectors are used to measure pressure changes occurring in enclosed gases, liquids, or solids being excited by intensity or frequency modulated electromagnetic radiation. Radiation absorption spectra, collisional relaxation rates, substance compositions, and reactions can be determined from the time behavior of these pressure changes ...

Pulsed optoacoustic spectroscopy of NADH
Analytical Biochemistry, 1981Abstract Optoacoustic spectroscopy is a potentially powerful tool for the determination of trace and ultratrace components of biochemical interest. We derive here an abbreviated theory of pulsed optoacoustic spectroscopy, describe the experimental apparatus, and report on the performance in the determination of NADH.
