可获得高衬比干涉条纹的实时全息记录方法
A REAL-TIME HOLOGRAM RECORDING METHOD FOR OBTAINING HIGH CONTRAST OF INTERFERENCE FRINGES
【摘要】 本文提出了一种可以获得高衬比的实时全息记录方法,它通过分析所记录的第一张实时全息图来获得拍摄最佳衬比实时全息图的拍摄参数,文中指出了拍摄最佳衬比实时全息图需要满足的条件,给出了理论分析和实验验证,实验结果与理论相符甚好,对于透明物体的实时法全息图.条纹衬比可接近最佳值1.
【Abstract】 A real-time hologram recording method for obtaining high contrast of interference fringes is proposed in this paper.The related parameter of how shooting a contrast improvement real-time hologram can be obtained by analysing the real-time hologram which was recorded at the first time. The theoretical analysis and experimental demonstrations of this method are also introduced.A real- time hologram with high contrast of interference fringes can be shot by using this method.In case of a transparent object,the optimum contrast of fringes can reach to 1.
