Detecting Subsidence Along a High Speed Railway by Ultrashort Baseline TCP-InSAR with High Resolution Images
SAR PS-InSAR TCP-InSAR High resolution Subsidence Detecting Phase Unwrapping High Speed Railway
2014/4/22
A High Speed Railway goes across Wuqing district of Tianjin, China. Historical studies showed that the land subsidence of this area was very serious, which would give rise to huge security risk to the...
Fiber Based Ultrashort Pulse System with Kilowatt Level Average Power
Fiber optics amplifiers oscillators Ultrafast Lasers
2015/6/9
We report on the generation of 830 W of compressed average power at 78 MHz pulse repetition frequency and 640 fs pulse duration. We discuss further power scaling including the issue of transversal spa...
