| 2. | So we can say that everywhere use polarized light technique can hardly work without optical phase retarders
可以说几乎所有应用偏光技术的地方都离不开光相位延迟器。 |
| 3. | The common are quarter - wave plate and half - wave plate . fitted with other polarimetric elements , they can realize converting and rotating of polarization states , and modifying of all kinds of light wave
光相位延迟器同其他偏光器件相配合，可以实现光的各种偏振态之间的相互转换、偏振面的旋转以及各类光波的调制。 |
| 4. | Firstly , this paper introduces the molecule ’ s structure , the molecule ’ s spectrum and infrared spectrum structure of so2 , and then the theory of gas detection using photoacoustic effect is discussed
本文从分子结构和分子光谱理论出发讨论了so2的红外光谱结构，介绍了气体光声光谱检测理论及光纤光相位调制解调的技术和方法。 |
| 5. | Therefore somebody put forward the design of achromatic optical phase retarders whose retardation are insensitive to wavelength . due to the less dependence on wavelength , this kind of optical phase retarders have an extensive used perspective
光相位延迟量与波长无关的延迟器称为消色差延迟器，消色差延迟器削弱了相位延迟量对波长的依赖程度，有着广阔的应用前景。 |
| 6. | After comparing main advantage and disadvantage of all theories of gas concentration measurement , this thesis chooses so2 as object to research a kind of so2 concentration measurement apparatus on the base of theory of photoacoustic effect and the optical fiber phase modulated mechanism
本文在分析各种气体浓度检测方法的主要优缺点的基础上，选择二氧化硫( so2 )作为研究对象，研究一种应用光声光谱原理和光纤光相位调制机理相结合的气体浓度监测仪。 |
| 7. | 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。 |
| 8. | Optical phase retarders are not only important optical components in laser technique and polarized light technique fields , but also the basic optical phase modulators that introduce a phase shift between orthogonal and linearly polarized component when light transmittes through them
光相位延迟器，是偏光技术和激光技术领域中极为重要的光学器件，也是最基本的光相位调制器。它能使透过它的振动方向相互垂直的两束光波彼此之间产生一定的相位差，故称光相位延迟器。 |
