|Abstract:||Miniaturized low-power, high-speed scanners are tremendously useful in a variety of applications. Besides MEMS micromirrors, the in-plane vibratory grating scanner is a development in this area which possesses several unique features. The in-plane scanning mechanism minimizes the dynamic non-rigid-body out-of-plane deformation of the mirror surface, allowing for higher-resolution displays. The dispersive element permits splitting the incoming beam into its constituents for analysis. Coupling a grating platform to an in-plane moving structure is also useful for real-time motion measurement which would otherwise be difficult to pick-up. The past developments till the current design are explored in this paper. Possible alternative applications besides image display, for example spectral imaging and realtime motion sensing are also described. © 2011 Copyright Society of Photo-Optical Instrumentation Engineers (SPIE).|
