摘要
用付立叶光学原理，从理论与实践讨论了二维付立叶交换光学系统的空间带宽积的物理意义。首次提出了具有重要实用价值的敏感空间带宽积概念。并介绍了它的主要应用。
The Spatial -Band width product of 2-D Fourier transform optics system has been discussed dinal in this paper. The sensitive S-B product of Laser particle size analyser was put forward in first place, which is important in the design, research and use for this analyser.
