Abstract

An electron beam addressed spatial light modulator using 55 degree cut LiNb0₃ for both coherent and incoherent light modulation is reported. The device is compact and can be operated fully electronically since it incorporates a single electron gun for writing and erasing operations. With this device, a resolution of 3 1p/mm at 50 % modulation, 13 1p/mm at 5 % modulation, a cycle time of 1/30 second and contrast ratio of greater than 1000 : 1 ( coherent) and 20 : 1 (incoherent) are achieved. The device can be used in many applications such as radar and sonor processing, microwave holography, transducer for electric serial signal to optical parallel signal and large screen display.
