Abstract

Volume holographic recording of complex images with a double phase-conjugation mirror in a fiberlike Bi(12)TiO(20) single crystal, mutually pumped by two separate He-Ne lasers, is experimentally demonstrated. Complex images can be stored and reconstructed by use of even a partial input image. The advantages of the small-cross-section, light-confining photorefractive sample in comparison with bulk crystal are a wider spatial bandwidth of recorded images and the possibility of recording holograms by application of smaller ac voltages.

摘要

通过在纤维状Bi(12)TiO(20)单晶中使用双相位共轭镜对复杂图像进行体全息记录，由两台独立的氦氖激光器相互泵浦，这一过程已通过实验得到证实。即使使用部分输入图像，也可以存储和重建复杂图像。与块状晶体相比，具有小横截面、光限制特性的光折变样品的优点在于记录图像的空间带宽更宽，并且通过施加较小的交流电压就有可能记录全息图。
