Abstract
Frequency scanning interferometry (FSI) is an absolute distance measurement technique that offers high accuracy, stability, and potentially direct traceability to the international system of units, the SI. In this article we present an overview of the basic principles of FSI, how we are adapting the technology used in conventional single-target FSI, and how we are combining it with the technique of multilateration to develop a flexible, high-accuracy, self-calibrating six degree-of-freedom coordinate measurement system with inherent traceability to the meter. We present some initial results from a working prototype that currently operates over a spherical measurement volume of approximately 0.3 m in diameter, discuss the issues associated with extending the working volume, and reveal how these are being addressed.
