A noninvasive technique for imaging subsurface tissue structure with micrometer-scale resolution. The principles of time gating, optical sectioning, and optical heterodyning are combined to allow cross-sectional imaging. Depths of 1–2 mm (0.04–0.08 in.) can be imaged in turbid tissues such as skin or arteries; greater depths are possible in transparent tissues such as the eye.
