Abstract

Methods for generating optical coherence tomography intensity maps are provided. A beam of light is generated and divided along a sample path and a reference path. The sample path beam of light is directed to locations in an X-Y plane. Light returned from each of the sample path and the reference path is received. Sets of outputs are generated, each corresponding to light intensities received at different wavelengths of the light source when the beam of light is directed at a particular X-Y plane location, the light intensities including information about a light reflectance distribution within an object in a depth direction Z at the particular X-Y plane location. A set of outputs generated from directing the beam of light at a particular X-Y plane location is high-pass filtered to generate a set of filtered outputs suitable for generating a two-dimensional image intensity map of the object.
