2024年6月18日 · The optical levitation system employs a focused laser to trap particles, generating a gradient force that directs the particles toward the focal point. This enables a …

A laser-optical measurement system was developed to measure single blade tip clearances and average blade tip clearances between a rotor and its gas path seal in rotating component rigs …

a rotor gyroscope based on optically levitated high-speed rotating particles is proposed. In vacuum, an ellipsoidal vaterite particle with 3.58 µm average diameter is driven to rotate at …

2014年6月16日 · The Rolls-Royce BTT system uses casing-mounted laser spot probes to measure the arrival times of the blade set. The vibration amplitudes of the blades are then …

optical levitation system is built in a vacuum to realize ultrafast rotation of the trapped particle, and the gyro- scopic effect is validated by detecting the spin axis

2021年9月1日 · Optical trap, a circularly polarized laser beam can levitate and control the rotation of microspheres in liquid medium with high stiffness. Trapping force performs as confinement …

Abstract: Optical trap, a circularly polarized laser beam can levitate and control the rotation of microspheres in liquid medium with high stiffness. Trapping force performs as confinement while

Great length, large weight and other factors may cause difficulty in measuring the profile accuracy of the double-headed screw rotor. To solve this problem, an on-machine measuring system …
