Primary accelerometer calibration with two-axis automatic positioning stage
Wataru Kokuyama, Tomofumi Shimoda, Hideaki Nozato
In this study, we developed an automated, multipoint primary accelerometer calibration system using a two-axis positioning stage and a heterodyne laser interferometer. The proposed…
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…
