色散现象 meaning in Chinese

chromatic dispersion

Test methods for chromatic dispersion of optical fibers

The new idea on studying the phenomenon of photic vacuum dispersion
研究光的真空色散现象时的一个新观点
Conventional optical phase retarders are mostly designed by birefringent material . the refractive indices depend on the wavelength so strongly that the retardation is close to wavelength , here we call this dependent relationship the birefringent dispersion of material . this is the reason why conventional optical phase retarders are mostly applied to a single wavelength but ca n ' t be used to varied wavelength , so they are inconvenient to handle
常规的光相位延迟器是由双折射材料制成的，由于材料的双折射率同波长密切相关，使其产生的相位延迟量也同波长具有严格的一一对应关系(即材料的色散现象) ，因而常规相位延迟片多用于单一波长，不同波长之间使用不可兼顾，这在使用中带来诸多的不便。
