LCD Real-Time Mask Technique for Fabrication of Continuous Microoptical Elements
new technique for fabrication of continuous microoptical elements by using LCD (liquid crystal display) real-time mask is proposed, and its principle and design method are expatiated. Based on partial coherent imaging theory, the process to fabricate the micro-axicon and the microlens has been simulated. The experimental setup for LCD real-time mask technique was built by using the color LCD in authors′ laboratory. and the micro-axicon array has been fabricated. The 3|dimensional surface relief structure was shaped in the pan chromatic silver-halide sensitized gelatin (Kodak-131) with trypsinase etching. The caliber of axicon is 118.7 μm, and the etching depth is 1.322 μm
