摘要
本文论述光波场的时问、空间对称性,包括拍频导致的“空间放大”与“时间放大”;多束光干涉提高条纹细锐度“空间压缩”、锁模技术中脉冲的“时间压缩”;空间调制与时间调制;非线性效应中的时间倍频与空间倍频;空间相干性与时间相干性;时域测不准与空域测不准。
In this paper the temporal and spatial symmetry of opticall field includes te-mporal and spatial amplify produced by beat of optical wave, spatial compactproduced by decreasing the thickness of fringe of multipe-beam interference andtemporal compact produced by optical pulses in mode-lock technology, spatialand temporal modulation, temporal and spatial multiplexing in nonlinear effect,spatial and temporal coherente, and spatial and temporal uncertainty.
