Miniature displays based on scanning a low power beam directly onto the viewer's retina can offer high spatial and color resolution and very high luminance. For scanning display systems, the resolution is primarily determined by the product of scan-angle and mirror-size (OD-product). Once 8D is determined based on resolution requirements, it then remains to choose D and B. The choice of D and has a big impact in scanner design and many factors need to be taken into account. This paper discusses how D and e should be chosen considering the limitations due to dynamic mirror deformation, stress in flexures, scanner frequency, optomechanical design, size, and cost.
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.
