Ninth International Symposium on Precision Mechanical Measurements, 2019
A method is presented in order to realize the measurement of angular position and angular speed simultaneously based on the theory of time grating. A model of angular speed measurement is built by using the Doppler Effect which is produced by relative uniform motion of bi-coordinate system inside the time grating. Measure benchmarks of angular position

Review of Scientific Instruments, 2014
This paper presents the theory and implementation of a novel sensor system for measuring the angular speed (AS) of a shaft rotating at a very low speed range, nearly zero speed. The sensor system consists mainly of an eccentric sleeve rotating with the shaft on which the angular speed to be measured, and an eddy current displacement sensor to obtain ...

Sailcraft at high speed by orbital angular momentum reversal
Acta Astronautica, 1997Abstract Considering a photon solar sail spacecraft with a lightness number (λ) in the range [0.5-1) (all-metallic sails), this paper analyses a class of heliocentric trajectories, characterized by orbital angular-momentum reversal, delivering a considerable final spacecraft speed.
