Ultrahigh-resolution full-field optical coherence microscopy using InGaAs camera.
Full-field optical coherence microscopy (FFOCM) is an interferometric technique for obtaining wide-field microscopic images deep within scattering biological samples. FFOCM has primarily been implemented in the 0.8 mum wavelength range with silicon-based cameras, which may limit penetration when imaging human tissue. In this paper, we demonstrate FFOCM at the wavelength range of 0.9 - 1.4 mum, ...
متن کاملSpectroscopic ultrahigh-resolution full-field optical coherence microscopy.
We have developed a full-field optical coherence microscopy system providing intensity-based tomographic images and spectroscopic information with ultrahigh spatial resolution. Local measurements of the backscattered light spectrum center of mass are achieved through short-time Fourier analysis of a stack of en face interferometric images acquired with a Linnik-type microscope. Using a halogen ...
متن کاملUltrahigh-resolution full-field optical coherence tomography using spatial coherence gating and quasi-monochromatic illumination.
We developed an ultrahigh-resolution full-field optical coherence tomography (FF-OCT) microscope that is based on the spatial, rather than the temporal, coherence gating. The microscope is capable of observing three-dimensional microbiological structures as small as 0.4 μm × 0.4 μm × 1.0 μm (xyz) using quasi-monochromatic light and a liquid crystal retarder. Unlike traditional FF-OCT systems, t...
متن کاملFull-Field Optical Coherence Microscopy
Optical coherence tomography (OCT) is a well-established optical imaging technique with micrometer-scale resolution. OCT is based on low-coherence interferometry to measure the amplitude of light backscattered by the sample being imaged [1-4]. The most significant impact of OCT is in ophthalmology for in situ examination of the pathologic changes of the retina [5-8] and measurement of the dimen...
متن کاملUltrahigh-resolution optical coherence tomography.
In the past two decades, optical coherence tomography (OCT) has been established as an adjunct diagnostic technique for noninvasive, high-resolution, cross-sectional imaging in a variety of medical fields. The rapid development of ultrabroad bandwidth light sources has recently enabled a significant improvement in OCT imaging resolution, demonstrating the potential of OCT to accomplish its orig...
