产品名称：LC-R 720 空间光调制器(反射)

产品简介：

LC-R720空间光调制器是基于一个反射LCOS微型显示器用的1280×768像素（WXGA）的分辨率。为20μm的像素间距和92％的填充因子在LC-R720表示的70％左右在可见光的反射率。对<3毫秒和180赫兹的高图像帧速率非常快的响应时间，使LC-R720空间光调制器用于高速应用，例如面板颜色顺序投影一个不错的选择。除了投影应用在LC-R720也可以被用于相位调制。该装置提供约1Pi在可见光的相移。例如（~1.2Pi@532nm）

The LC-R 720 Spatial Light Modulator is based on a reflective LCOS microdisplay with a resolution of 1280×768 pixel (WXGA). With a pixel pitch of 20µm and a fill factor of 92% the LC-R 720 shows a reflectivity of around 70% in the visible. The very fast response time of < 3ms and the high image frame rate of 180 Hz makes the LC-R 720 Spatial Light Modulator a good choice for high speed applications such as one panel color sequential projection. Besides projection applications the LC-R 720 can also be used for phase modulation. The device provides a phase shift around 1 Pi in the visible (e.g. ~1.2Pi @ 532 nm).

LC-R 720 Spatial Light Modulator – Software Features:

The LC-R 720 spatial light modulator can simply be addressed like an external monitor using the standard DVI interface of the graphics card. No additional software or dedicated hardware is needed to operate the SLM.

The LC-R 720 SLM is delivered with a GUI (Graphical User Interface) based calibration software. The calibration software can be used to change geometrical settings, brightness, contrast and the electrooptical response by applying a new gamma curve. For these advanced callibrations the RS232 interface has to be connected via a servial COM port of the computer (there are also USB to COM adapters available).

In addition a HOLOEYE SLM Application Software is provided with the device. Key features of which are:

Computation of computer generated holograms (CGH) from user defined images

generation of SLM signals representing basic optical functions such as lenses, gratings, axicon and vortex functions

superposition of CGH’s with basic optical functions to combine functionalities
