| 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 realtime 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. |
