Abstract
An optical coherence tomography (OCT) system having magnitude and direction of motion detection has a light source, and a scanning system arranged in an optical path of the light source. The scanning system is configured to scan an illumination beam of light in a spatial pattern around each of a plurality of points of interest of an object under observation for a corresponding plurality of instants of time in which each of the plurality of points of interest are displaced from each other due to motion of at least one of the OCT system or the object under observation. The OCT system also includes an OCT detection system configured and arranged to receive at least a portion of the illumination beam of light after being at least one of reflected or scattered from said the under observation, and a signal processor configured to communicate with the OCT detection system to receive detection signals therefrom. The signal processor is configured to process the detection signals to determine both magnitude and direction of relative motion of the OCT system from a first one of the plurality of points at a first corresponding time to a second one of the plurality of points at a second corresponding time.
