Abstract: Embodiments of the present invention provide a method and apparatus for frequency-domain optical interferometry imaging. Embodiments of the invention include an apparatus comprising a line-shaping optical element for directing optical radiation into a line illumination, an imaging optical element for receiving optical radiation comprising radiation reflected from a target sample and a reference point associated with the target sample, and a detection unit for measuring common path interferences between a plurality of reflections from the target sample and the reference point. Embodiments of the invention include a method comprising directing radiation into a line illumination, directing the line illumination towards a target sample, receiving radiation reflected from the target sample at a detection unit, and measuring common path interferences between a plurality of reflections at the target sample and a reference point.
