Abstract

An imager that can provide separated images corresponding to differing depths in a sample is presented. In accordance with some embodiments of the invention, an imager can include a light source; a sample arm that receives light from the light source, directs the light to a sample, and captures light returning from the sample; a modulation source that provides different modulations corresponding to differing imaging depths in the sample; a detector system to receive the captured light from the sample with the different modulations; and a processor that receives signals from the detector system and separates a plurality of images corresponding with the differing image depths in the sample.
