The invention provides a hybrid OCT scanning device which improves OCT scanning of targets, including adaption for a ophthalmic targets (i.e. cornea, retina and fovea areas). The invention provides a movable beam modifying element which is adapted to be interposed in the probe radiation directed to the target, and the interposition of the movable element is synchronous with the periodicity of the OCT scan beam. The beam modifying element may include any of angular deflection regions, optical delay regions, or combinations of deflection and delay regions. Such regions of deflection and/or delay translate into a governable scan range, both lateral and depth, of a target region.
