Photoacoustics with coherent light

Since its introduction in the mid-nineties, photoacoustic imaging of biological tissue has been one of the fastest growing biomedical imaging modality, and its basic principles are now considered as well established. In particular, light propagation in pho ...

Fluorescence and optical-resolution photoacoustic imaging through capillary waveguides

Demetri Psaltis, Christophe Moser, Salma Farahi, Nicolino Stasio, Emmanuel André Henri Bossy

Endoscopy can be used to obtain high-resolution images at large depths in biological tissues. Usually endoscopic devices have a diameter ranging from 1 to few millimeters. Using digital phase conjugation, it is possible to adapt ultrathin multimode fibers ...

Minimally Invasive Optical Photoacoustic Endoscopy with a Single Waveguide for Light and Sound

Demetri Psaltis, Ioannis Papadopoulos, Christophe Moser, Salma Farahi, Nicolino Stasio, Emmanuel André Henri Bossy

An endoscopic device for photoacoustic imaging, including a multimode optical fiber having a distal end and a proximal end, a light source to provide a light beam to the proximal end of the multimode optical fiber, a transducer to capture acoustic waves th ...

Optical-resolution photoacoustic imaging through thick tissue with a thin capillary as a dual optical-in acoustic-out waveguide

Demetri Psaltis, Christophe Moser, Nicolino Stasio, Emmanuel André Henri Bossy

We demonstrate the ability to guide high-frequency photoacoustic waves through thick tissue with a water-filled silica-capillary (150 mu m inner diameter and 30 mm long). An optical-resolution photoacoustic image of a 30 mu m diameter absorbing nylon threa ...

Towards new applications using capillary waveguides

Demetri Psaltis, Christophe Moser, Salma Farahi, Nicolino Stasio, Emmanuel André Henri Bossy

In this paper we demonstrate the enhancement of the sensing capabilities of glass capillaries. We exploit their properties as optical and acoustic waveguides to transform them potentially into high resolution minimally invasive endoscopic devices. We show ...

Optical-resolution photoacoustic microscopy by use of a multimode fiber

Demetri Psaltis, Christophe Moser, Salma Farahi, Emmanuel André Henri Bossy

We demonstrate Optical-Resolution Photoacoustic Microscopy (OR-PAM), where the optical field is focused and scanned using Digital Phase Conjugation through a multimode fiber. The focus is scanned across the field of view using digital means, and the acoust ...
