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 9):
An apparatus of step scanning a chirped laser beam by combining continuous scanning and dispersive counter-scanning comprising:\n a light source comprising a first chirped laser component, continuously changing the laser wavelength and resetting the wavelength to complete a chirp cycle, and repeating multiple chirp cycles; a first sensing laser beam consisting of at least a portion of the first chirped laser component; a first dispersive component dispersing the first sensing laser beam, and creating a first reciprocating dispersive beam moving due to the wavelength chirping and resetting; a beam scanning device; a beam scanning function programming the beam scanning device to transversely scanning the first sensing laser beam continuously along a direction reversing the dispersive moving direction during the chirp periods;
