Abstract:Using DMD system to make circular gratings and arrays is based on the character of Space Light Modulation (SLM) of DMD chip which can control the reflected lights based on the input figures' gray-scale. Firstly, circular gratings are simulated in a computer with some simulation software programmed in VC. Then, the figures are inputted in the DMD chip. With the character of SLM of DMD chip, the reflected lights can be controlled according to the circular gratings' gray-scale. The circular gratings can be obtain… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
