Research Institution
The goal of this Phase I project is to develop an affordable, accurate, and rapid absolute interferometric length measurement technique with improved repeatability and accuracy. API has a patent-pending technology, Frequency-Modulated Time-to-Frequency Mapping Interferometer (FM-TFMI), that is an absolute interferometer capable of measuring at high speed and with exceptionally high accuracy. The TFMI uses a fiber Bragg grating to provide great system design flexibility in terms of scalability of measurement range that no other methods can possibly afford without compromising measurement accuracy or speed. In Phase I, we demonstrate its capability in terms of range, accuracy, repeatability and speed.
