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.

Step-scanning sensing beam for imaging interferometer

A method for terminating a plurality of optical fibers arranged in a two-dimensional arrangement comprises inserting the plurality of optical fibers into and through a fiber ferrule, where the fiber ferrule has a plurality of parallel channels extending from an entry surface through to a polish surface; polishing the polish surface including an end of each of the plurality of optical fibers to form a coplanar surface at a polish angle relative to a reference plane perpendicular to the parallel channels; and affixing a glass plate to the polish surface.
