產(chǎn)品簡介：
LC-R720空間光調(diào)制器是基于一個(gè)反射LCOS微型顯示器用的1280×768像素（WXGA）的分辨率。為20μm的像素間距和92％的填充因子在LC-R720表示的70％左右在可見光的反射率。對(duì)<3毫秒和180赫茲的高圖像幀速率非常快的響應(yīng)時(shí)間，使LC-R720空間光調(diào)制器用于高速應(yīng)用，例如面板顏色順序投影一個(gè)不錯(cuò)的選擇。除了投影應(yīng)用在LC-R720也可以被用于相位調(diào)制。該裝置提供約1Pi在可見光的相移。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:
-2.png)
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
