A new algorism of computer holography utilizing the anisotropic interaction of light with photodichroic materials is proposed. The most unique feature of this technique lies in the realization of phase information recording without the use of detour phase or optical path difference effect. Basic principles of information recording and reconstruction scheme using M centers in alkali halide crystals such as sodium fluoride are described in detail, and several technical merits and problems associated with the proposed algorism are discussed. This new method will provide a real-time holographic system where accurate recordability and high storage capacity are attainable due to its possibility of recording a calculated complex amplitude of wavefront only by means of controlling the polarization direction of illuminating beam.
提出了一种利用光与光致变色材料的各向异性相互作用的计算机全息新算法。该技术最独特的特点在于无需使用迂回相位或光程差效应即可实现相位信息记录。详细描述了使用碱金属卤化物晶体(如氟化钠)中的M中心进行信息记录和重建方案的基本原理,并讨论了与该算法相关的几个技术优点和问题。这种新方法将提供一种实时全息系统,由于其仅通过控制照明光束的偏振方向就有可能记录计算出的波前复振幅,因此可以实现精确的可记录性和高存储容量。
