光学双稳装置在体积反射全息图片拍摄中的应用
The Application of the Bistable Optical Device in Taking Reflecting Hologram
【摘要】 外界扰动常造成干涉条纹的随机漂移,在拍摄体积反射全息时,如果记录时间较长,那么干涉条纹随机漂移的影响将会变得十分严重,使全息图片质量下降。我们提出用光学双稳装置来作条纹稳定器。建立一个与物光和参考光相近的迈克尔逊干涉光路作调制函数,用压电陶瓷作电光反馈函数。实验结果表明干涉条纹的漂移得到很好的控制,所拍摄全息图片的信噪比得到较大的提高,降低了对拍摄环境的要求,拍摄的成功率也大大提高。
【Abstract】 The external vibration usually cause the random movement of interference fringe.In taking the reflecting hologram,the movement of interference fringe will lower the quality of hologram for long time exposure.In this paper,the bistable optical device with opticalelectro feedback is used for fringe stabilized system.By use of the Michelson interference of the object light and the reference light for modulation function and piezoelectrical ceramic for feedback function,the movement of interference fringe can be better control and the quality of reflecting hologram is increased,for example:signal to noise,stability,the possibility of success.
【Key words】 reflecting hologram; interference fringe; bistable optical device; phase compensation;
