LCOS-SLM(空间光调制器)
X15213 系列设备是一种反射型纯相位空间光调制器 (SLM),基于硅基液晶 (LCOS) 技术,其中液晶 (LC) 直接由电压进行准确控制,并且可以调制光束的波前。LCOS-SLM 经过精心设计,可从各种角度(例如反射率、孔径比和像素结构引起的衍射噪声)实现高光利用效率。X15213 系列可通过使用数字视频接口 (DVI) 的 PC 进行控制,而 DVI 是 PC 显示器的标配接口。LCOS 芯片中的失真(如 LC 的波前失真和非线性响应)可通过控制器进行高效校正。使用 X15213 系列可实现简便的 PC 控制、精确的线性相位调制特性。它们还可以提供高衍射效率和高光利用率。
