Abstract
We report the first demonstration of high resolution mm dynamic range measurements using sinusoidal phase modulation interferometry. Our novel method has increased the range by over 3 orders of magnitude, while maintaining ultra-high accuracy. Simple commercial laser diodes were used and a new algorithm allowed for the first ultra-high accuracy and high dynamic range in real time for a slightly vibrating environment.
