During femtosecond laser fabrication, photons are mainly absorbed by electrons, and the subsequent energy transfer from electrons to ions is of picosecond order. Hence, lattice motion is negligible ...
Entangled atoms, separated in space, are giving scientists a powerful new way to measure the world with stunning precision.
The 164-ft-long FPE raises the rocket vertically, aligns it, and transfers it onto the launch table. Operation is somewhat like a drawbridge, with more than two dozen precision interfaces requiring ...
China has successfully conducted its first satellite laser ranging at Earth-Moon distance, marking a milestone in its deep-space exploration capabilities, the Chinese Academy of Sciences announced on ...
Abstract: Frequency Modulated Continuous Wave (FMCW) LiDAR systems require the precise generation of linear chirp signals for high-resolution distance measurements. While previous studies have ...
Abstract: High-precision 3-D topography is essential for surface profile detection in chips, precision optical lenses, and other components. A nanometer-scale laser interferometric distance sensor ...
