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.

Optoacoustic imaging and potential applications of raster-scan optoacoustic mesoscopy in dermatology
Clinics in Dermatology, 2022Optoacoustic imaging (OAI) is a hybrid imaging modality that integrates the benefits of optical contrast and ultrasound detection. Raster-scan optoacoustic mesoscopy (RSOM) is an emerging OAI method that provides information about several dermatological conditions' structural, functional, and molecular features.

Optoacoustic monitoring of bilirubin photodegradation
Journal of Biophotonics, 2023AbstractHematomas resulted from trauma are very common, and the efficacy of existing treatment techniques is limited. Phototherapy can be used to expedite healing and improve the appearance of the damaged tissue. Efficient phototherapy requires determination of chromophore composition in hematoma, which can be provided by the optoacoustic (OA ...

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

Doppler-free optoacoustic spectroscopy
Optics Communications, 1979The first observation of Doppler-free optoacoustic spectroscopy is reported. As a first example the P (193) line of the 11-0 band of the B←X transition of 127I2 is used. The output of cw single mode dye laser is split into two equal intensity beams chopped at frequencies ω1 and ω2. The nonlinear compoment of the optoacoustic signal at the frequency (ω1

Optical and Optoacoustic Imaging Probes
2020Tissue has characteristic properties when it comes to light absorption and scattering. For optical (OI) and optoacoustic imaging (OAI) these properties can be utilised to visualise biological tissue characteristics, as, for example, the oxygenation state of haemoglobin alters the optical and optoacoustic properties of the molecule.

Image Reconstruction in Optoacoustics.
2015This thesis investigates reconstruction techniques for optoacoustic (oa) imaging, implemented both in pulsed and continuous wave (cw) mode. Two approaches to incorporate the transducer geometry into model-based reconstruction are implemented and its benefits showcased in simulations and experiments.
