The possibilities of designing optical devices for data processing and imaging based on the manipulation of coherent light beams by means of spatial light modulators (SLMs) are investigated. A review of commercially available SLMs is presented and the limitations of their complex modulation characteristics are analysed. The main problem of using present-day SLMs is the lack of the ability to modulate directly all states within a unit circle in the complex plane. In this regard, the characteristics of current methods for the synthesis of holographic elements are described that implement a given complex impulse response of the optical system and are optimal for using SLMs with purely amplitude, purely phase, and hybrid amplitude – phase modulation.

用于计算机合成全息元素以获得基于现代空间光调制器的光学信息处理系统的复杂脉冲响应的方法和算法

研究了通过空间光调制器（SLM）对相干光束进行操纵来设计用于数据处理和成像的光学设备的可能性。提出了对商用SLM的综述，并分析了其复杂调制特性的局限性。使用当今的SLM的主要问题是缺乏直接调制复杂平面中单位圆内所有状态的能力。在这方面，描述了用于全息元件合成的当前方法的特征，这些方法实现了光学系统的给定复杂脉冲响应，并且最适合用于具有纯振幅，纯相位和混合振幅-相位调制的SLM。
