An All-Fiber-Optic Combined System of Noncontact Photoacoustic Tomography and Optical Coherence Tomography

We propose an all-fiber-based dual-modal imaging system that combines noncontact photoacoustic tomography (PAT) and optical coherence tomography (OCT). The PAT remotely measures photoacoustic (PA) signals with a 1550-nm laser on the surface of a sample by utilizing a fiber interferometer as an ultrasound detector. The fiber-based OCT, employing a swept-source laser centered at 1310 nm, shares t...

Fiber-optic-bundle-based optical coherence tomography.

A fiber-optic-bundle-based optical coherence tomography (OCT) probe method is presented. The experimental results demonstrate this multimode optical fiber-bundle-based OCT system can achieve a lateral resolution of 12 microm and an axial resolution of 10 microm with a superluminescent diode source. This novel OCT imaging approach eliminates any moving parts in the probe and has a primary advant...

Inverse problems of combined photoacoustic and optical coherence tomography

Optical coherence tomography (OCT) and photoacoustic tomography are emerging non-invasive biological and medical imaging techniques. It is a recent trend in experimental science to design experiments that perform photoacoustic tomography and OCT imaging at once. In this paper, we present a mathematical model describing the dual experiment. Because OCT is mathematically modelled by Maxwell's equ...

Noncontact goniometry with optical coherence tomography.

OBJECTIVE To assess the value of noncontact goniometry with optical coherence tomography (OCT) compared with current clinical parameters in the evaluation of the anterior chamber angle (ACA). DESIGN Prospective observational study of 138 eyes of 109 patients. METHODS The ACA parameters and angle-opening distance (AOD) were measured with slitlamp-adapted OCT goniometry. The iris and scleral ...

Optical coherence tomography by all-optical MEMS fiber endoscope

This paper presents the first successful demonstration of all-optical MEMS (microelectromechanical system) fiber endoscope for OCT (optical coherence tomography) measurement. A MEMS optical scanner for spatial light modulation has been assembled in the endoscope probe head (φ 6mm) with optical components and a photovoltaic cell. Actuation energy for the MEMS scanner is optically supplied by usi...
