Abstract

Phase shift profilometry has become a standard technique for recording the surface of an object using the projection of sinusoidal patterns. We present a method of projecting the patterns via a pair of single-mode optical fibers mounted within a needle. The system presented can capture sub-millimetre precision depth profiles at 60 frames per second. The key features of the system that enable the high-speed imaging are the creation of an automated calibration system and developments in the image unwrapping and reconstruction algorithms to produce high fidelity surface measurements. These methods produce a compact projection system capable of accurate and fast profilometry.
