Sentence examples for measure phase difference from inspiring English sources

Different from the traditional way of using piezoelectric (PZT) phase shifter to measure phase difference, a new method is designed to calculate it between signals in the two arms of a homodyne fiber interferometer.

To measure phase difference for imaging, we use a grating-based interferometer ("Talbot" type, (Momose et al., 2003)) (Fig. 1).

Critical to our technique is the ability to measure phase differences between reflective layers located at different retinal depths.

In the database, the phase difference vectors corresponding to a same elevation angle are chosen, measured phase difference vector is correlated to these sample vectors.

Fig. 4 LogErr measured phase difference between clean and noisy cross-PSD at a low frequencies (below 1 kHz) and b high frequencies (from 1 to 8 kHz) and LogErr measured scaling difference between clean and noisy cross-PSD phase applied at c low frequencies and d high frequencies.

where f is a function that used to measure the similarity between measured phase difference vector and the one in database, which is called as similarity function.

The faced problem thus is how to determine the unique direction of incident wave according to several measured phase differences precisely.

Above equation means the correlation coefficients between sample vector and measured phased difference vectors with the same azimuth are same.

We then measure certain frequencies our switching scheme injects into, which allows us to measure the phase difference between different antennas.

In this study, a phase quadrature interferometer is designed to measure the phase difference variation proportional to the optical rotation.

An astute reader might point out that the signals from each antenna are already different, and that if we have access to the signal from each antenna we should be able to measure the phase difference directly.
