Abstract
One embodiment of the present invention is an optical coherence tomography (“OCT”) application apparatus that performs an OCT application on an object. The OCT application apparatus includes: (a) an OCT scanning apparatus which outputs a scanning beam of OCT scanning radiation; and (b) an active tracking system that generates and projects a tracking beam of tracking radiation onto a region including a reference tracking feature; wherein the active tracking system further includes an analysis system that analyzes tracking radiation reflected from the region to detect movement of the object and to generate tracking signals, and applies the tracking signals (i) to direct the active tracking system to move the tracking beam to follow the movement of the object, and (b) as input to the OCT scanning apparatus, to direct the OCT scanning apparatus to move the scanning beam to follow the movement of the object.
