Plans to improve the experimental limit in the comparison of the east-west and west-east one-way light propagation times on the rotating earth

摘要: The preceding paper describes the results so far (interrupted in Spring of 1989 because lack funds) an experiment comparing one-way light propagation times on surface rotating Earth. For 20 Km path length component East-West direction predicted difference between opposite sense would be 160 ps, if approximately 360 Km/s speed Earth gives effective speeds 3 x 10(exp 8) m/s +/- m/s. This could lead to a prediction clock transport and pulse synchronization methods described paper: delta(T) = 0.5 (160) 80 ps. current upper bound 100 ps for is limited by poorly understood systematic errors. most important seems intensity-dependent time delays remote avalanche photo-diode detector. will replaced continuously operating circular scan streak camera having single photon sensitivity resolution 5 (This has recently been developed Xian Institute Optics Precision Mechanics P.R.C.). Better isolation from shocks vibration Sigma-Tau hydrogen maser during provided. It hoped that less than can achieved.
