空間光調(diào)制器

CRi Spatial Light Modulator

在可見(jiàn)或近紅外光束同時(shí)調(diào)制相位和振幅，且不需要移動(dòng)部件。這些空間光調(diào)制器(SLMs)是被證明是行業(yè)的設(shè)計(jì)，并且提供single-mask和dual-mask配置相位，振幅，或同時(shí)階段/振幅脈沖整形。

主要特點(diǎn)：

·固態(tài)，快速，無(wú)振動(dòng)操作

·Single-mask或dual-mask液晶設(shè)計(jì)相位，振幅，或同時(shí)相位/振幅控制

·可見(jiàn)或近紅外波長(zhǎng)范圍

·較小的SLM - 128外殼更容易集成

·USB接口與自由軟件開(kāi)發(fā)工具包(SDK)高效低功耗操作和軟件集成
