Abstract:
In interferometer imaging signal acquisition using a movable optical beam to sample a target with specular or non specular reflecting surfaces or internal features, beam moving during interferometer signal acquisition can generate unwanted phase error due to shifting speckle field. Examples include coherent LIDAR, Interferometry Doppler sensing and optical coherence tomography. During an interferometer signal acquisition period, an interferometer sensing beam can be substantially stationary, and active step-scanning can be synchronized with interferometer signal acquisition cycles. For interferometers using repetitive chirping lasers, passive dispersive counter-scan mechanisms can be used to assist step-scanning operation.

Claim (Index 5):
An apparatus for transversely step scanning an interferometer sensing beam by combining continuous scanning and repetitive counter-scanning comprising:\n a light source; a beamsplitter splitting the light source into a reference beam and a sensing beam; a first beam moving device moving the sensing beam transversely; a second beam moving device moving the sensing beam in the same plane of the first beam moving; a transmitting aperture transmitting the sensing beam out of the apparatus and projecting a beam spot at a target location, with a resolvable beam width along the beam moving direction; a receiving aperture collecting a feedback beam from the target location; a beam combining device combining at least a portion of the reference beam and at least a portion of the feedback beam to form an interferometer signal; a motion controlling function programming the first beam moving device to scan the sensing beam continuously along a beam scanning direction, and programming the second beam moving device repetitively to move the sensing beam in the opposite direction of the beam scanning direction in periods of low beam moving speed and to move the sensing beam along the same direction of beam scanning direction in periods of high beam moving speed;
