光波二维相干度调制在两路光通信应用的研究

A Research, on Optical Waves Modulated by Degree of Two-Dimension Spatial Coherence in Double Channel Communication Applications

本文从理论上推导出了二维声行波对光空间相干度的调制结果,指出了利用双狭缝进行二维相干度解调的可行性。实验验证了光波的波前复用,借此可用一束激光实现两路通信。

In this paper , the theoretical result of the degree of spatial cohereneof optical waves modulated by two-dimension progressive ultrasonic wavecs has been obtained. The demodulation of optical waves with modulation degree of two-dimension spatial coherence is performed by double-slitt method. The wavefront multiplexing of optieal wave has been experimen tally confirmed , by which double-channel communication has been accomplished with singlelaser beam.
