摘要：This invention provides an angled-dual-axis optical coherence scanningmicroscope comprising a fiber-coupled, high-speed angled-dual-axis confocal scanning
head and a vertical scanning unit. The angled-dual-axis confocal scanning head isconfigured such that an illumination beam and an observation beam intersect optimallyat an angle &thgr; within an object and the scanning is achieved by pivoting the
illumination and observation beams jointly using a high-speed scanning element, therebyproducing an arc-line scan. The vertical scanning unit causes the angled-dual-axis confocalscanning head to move towards or away from the object. Optical coherence detection isemployed to provide temporal gating, thus detecting mostly single-scattered light andpreventing multiple-scattered light from dominating the signal when imaging in ascattering medium. By incorporating MEMS scanning mirrors and fiber-optic components,the angled-dual-axis optical coherence scanning microscope can be miniaturized toprovide a particularly powerful tool for in vivo medical imaging applications.
