【摘要】：光波經(jīng)過光學(xué)位移反射器后,由于全反射的存在,入射光的s偏振分量和p偏振分量在相位上將產(chǎn)生一個(gè)額外的常量差值,這將導(dǎo)致出射光相對(duì)于入射光的偏振狀態(tài)發(fā)生變化。通過分析高反膜的反射機(jī)理及其結(jié)構(gòu)特征,同時(shí)結(jié)合直角棱鏡的幾何結(jié)構(gòu),提出了基于高反膜膜系結(jié)構(gòu)的直角棱鏡保偏膜設(shè)計(jì)方法,該方法通過將設(shè)計(jì)膜系鍍制到直角棱鏡的兩直角面上,使光束經(jīng)過直角棱鏡平行反射后,偏振狀態(tài)保持不變。同時(shí),對(duì)該方法進(jìn)行了可行性研究和誤差分析。結(jié)果表明,該方法結(jié)合目前成熟的高反膜制作工藝,理論可行,易于實(shí)現(xiàn)商業(yè)化應(yīng)用;對(duì)于光波的小角度入射誤差而言,方案所述鍍膜直角棱鏡的保偏特性表現(xiàn)出良好的穩(wěn)定性。
[Abstract]:After the optical wave passes through the optical displacement reflector, due to the existence of total reflection, the S polarization component and the p polarization component of the incident light will produce an additional constant difference in phase, which will result in the change of the polarization state of the emitted light relative to the incident light. By analyzing the reflection mechanism and structural characteristics of high reflective film and combining the geometric structure of right angle prism, a design method for maintaining polarization film of right angle prism based on the structure of high reflective film system is proposed. By plating the design film on the two right angles of the right angle prism, the polarization state of the beam is kept unchanged after the beam is reflected parallel to the right angle prism. At the same time, the feasibility study and error analysis of the method are carried out. The results show that the proposed method is feasible in theory and easy to be applied commercially in combination with the current mature high reflective film fabrication process, and for the small angle incident error of light wave, The polarization maintaining property of the right angle prism of the coating shows good stability.
