1060 NM WAVELENGTH RANGE-BASED OPTICAL COHERENCE TOMOGRAPHY (OCT) SYSTEM FOR ANTERIOR/POSTERIOR SEGMENT IMAGING OF AN EYE

摘要

An OCT system for generating images of an anterior or posterior segment of an eye is described. The system includes a light source, a controller, optics, a detector, and a processor. The light source generates a beam of light and is capable of operating in a posterior or an anterior segment imaging mode. In the posterior segment imaging mode, the light source outputs light with a spectral bandwidth equal or narrower than the width of the 1060 nm water absorption window. In the anterior segment imaging mode, the light source outputs light with a spectral bandwidth larger than the width of the 1060 nm water absorption window. The controller enables switching between the posterior or anterior segment imaging mode. The optics scan the light over a set of transverse locations across the eye. The detector measures returning light and generates output signals for use by the processor to generate images.
