TL;DR: In this paper, an improved circumferential Fourier fit (ICFF) method is proposed, which is more consistent with reality than the traditional ICFF, and the simulated results showed that the ICFF performance is comparable to TCFF in terms of EO identification, except the lower PSR or more number probes that have a more negative effect on ICFF.

TL;DR: The presented IAD correlation method could be used for embedded, real-time, and automatic processing applications and Experimental results showed that the proposed method could identify all vibration events in rotating blades, even small events which may be wrongly identified by skillful operators.

TL;DR: Reconstruction conditions based on the MUSIC algorithm make the traditional MUSIC method overcome spectrum aliasing without expanding the snapshot matrix, and provides a feasible solution for the spectrum methods that cannot directly extract amplitude from the pseudo spectrum, such as the improved MUSIC, SDR-MUSIC, etc.

TL;DR: In this paper, a rotor-stator axial gap measurement method was proposed based on the phase difference ranging principle, where the structure of microwave heterodyne could effectively eliminate the errors caused by DC noise during absolute distance measurement.

TL;DR: In this article, the area of the ellipse calculated based on the two-parameter plot was derived for the first time in order to locate the vibration event using the area.
