Toward endoscopes with no distal optics: video-rate scanning microscopy through a fiber bundle.
نویسندگان
چکیده
We report a step toward scanning endomicroscopy without distal optics. The focusing of the beam at the distal end of a fiber bundle is achieved by imposing a parabolic phase profile across the exit face with the aid of a spatial light modulator. We achieve video-rate images by galvanometric scanning of the phase tilt at the proximal end. The approach is made possible by the bundle, designed to have very low coupling between cores.

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...
متن کاملBeam-scanning Multiphoton Multimodality Endoscopy
Two-photon-exciter fluorescence (2PEF) imaging and second-harmonic generation (SHG) microscopy has become well-established techniques for biomedical imaging [1]. Integration of fibers into the multiphoton microscopy system further enables in vivo and noninvasive investigation of biological samples. Nonetheless the broadening of ultrashort pulses in fibers has greatly hampered the development of...

We have recently demonstrated the modeling, design, and microfabrication process of a millimeter-scale, high-speed endoscopic scanner that is to be integrated at the distal end of an endomicroscope [1]. The scanner system consists of (1) an active Silicon optical bench (SOB), as shown in Figure 1, which constrains, aligns, and thermally actuates (1) mm-size optics (GRIN lens and prism) at 5 Hz ...
متن کاملSnapshot spectrally encoded fluorescence imaging through a fiber bundle.
Fiber optic endomicroscopy is a valuable tool for clinical diagnostics and animal studies because it can capture images of tissue in vivo with subcellular resolution. Current configurations for endomicroscopes have either limited spatial resolution or require a scanning mechanism at the distal end of the fiber, which can slow imaging speed and increase the probe size. We present a novel configu...
متن کاملAchieving stability in remote holography using flexible multimode image bundles.
Commercial flexible image bundles (boroscopes, endoscopes, etc.) are made up of tens of thousands of coherently arrayed multimode optical fibers whose modal propagation characteristics are unavoidably affected by bending losses. Consequently, light wave fronts transmitted through such bundles are subject to significant changes whenever the bundle is flexed anywhere along its length. For this re...
