Rapid Fabrication of Micro Optical Elements Using DMD-Based Maskless Lithography Technique
A low-cost microfabrication tool based on digital mirror device(DMD) is presented in this paper. The imaging principle of the system is described and the fabrication methods for binary and nonbinary micro optical elements(MOE) are also discussed in detail. It is expected to provide an understanding of MOEs fabrication using DMD-based maskless lithography technique.
