| Research Abstract |
We developed novel methods for controlling frequency, phase and timing of wide-range of frequency sources, such as from RF, THz, to optical frequencies using optical frequency combs based on mode-locked fiber lasers. Using developed techniques, we demonstrated several types of length measurements, together with a link between the results of an absolute distance measurement and an interferometeric measurement to show the principle of widening the range in high-accuracy length measurements.
