Abstract
A method for three-dimensional imaging stores a first image of field of view from a handheld optical coherence tomography (OCT) scanning device at a first position where a first OCT scan of an object is captured with the scanning device freely operated by a user. A location metric of a second image of field of view of the scanning device is estimated at a second position relative to the first image while the scanning device is moved from the first to the second position. Instructions on providing user feedback are generated based on the location metric. Feedback is provided to indicate if the second position is adequate for a second OCT scan, wherein providing feedback includes providing user perceivable light of a first color to indicate that the second position is adequate and providing user perceivable light of a second color to indicate that the second position is not adequate.
