Design of optical fiber phase retardation device
光纖相位延遲器的設計 -
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
常規的光相位延遲器是由雙折射材料製成的，由於材料的雙折射率同波長密切相關，使其產生的相位延遲量也同波長具有嚴格的一一對應關系（即材料的色散現象） ，因而常規相位延遲片多用於單一波長，不同波長之間使用不可兼顧，這在使用中帶來諸多的不便。 -
When the analyzer was located in four angles, a photoelectric detector was used to gather the energy of laser, so we can calculate the retardation of wave plate with the phase shifting
測量裝置採用了步進電機帶動檢偏器旋轉，運用光柵編碼器測角裝置測量檢偏器的轉動角度，使用光電探測器採集檢偏器在四個方位角度的光強值，根據移相演算法得出波片的相位延遲角。 -
By the use of the jones matrix of wave plates, the common measurement formula of wave plates was introduced, and a novel method based on phase shifting was proposed to measure the phase retardation for many kinds of wave plates
在波片測量時，無需被測波片的光軸和補償片的光軸成45要求，即不必知道波片的具體快慢光軸方位，只要將波片平行放入。 -
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
光相位延遲量與波長無關的延遲器稱為消色差延遲器，消色差延遲器削弱了相位延遲量對波長的依賴程度，有著廣闊的應用前景。
