1. A method comprising:
scanning an incident beam laterally across multiple beam locations of a target generating optical responses at various depths within the target;
imaging returned light resulting from the optical responses onto a light detector;
de-scanning the returned light so as to maintain a fixed position of the image on the light detector as the incident beam is scanned;
sampling images, each at a respective time, and processing each image to resolve depth information from each image; and
continuing the scanning to generate further images corresponding to each of the multiple beam locations and further processing the further images to resolve dynamic changes in the depth information.
