Phase meter based on zero-crossing counting of digitized signals
Wataru Kokuyama, Hideaki Nozato, Thomas R. Schibli
We developed a compact and easy-to-use phase meter based on a zero-crossing counting algorithm for digitized signals. Owing to the algorithm, the phase meter has low-noise and wide…
Simple digital phase-measuring algorithm for low-noise heterodyne interferometry
Wataru Kokuyama, Hideaki Nozato, Akihiro Ohta +1
We present a digital algorithm for measuring the phase difference between two sinusoidal signals that combines the modified fringe-counting method with two-sample zero crossing to…
Upper Limit on Gravitational Wave Backgrounds at 0.2 Hz with Torsion-bar Antenna
Koji Ishidoshiro, Masaki Ando, Akiteru Takamori +7
We present the first upper limit on gravitational wave (GW) backgrounds at an unexplored frequency of 0.2 Hz using a torsion-bar antenna (TOBA). A TOBA was proposed to search for l…
