A single-pixel spectral line imager based on a highspeed MEMS grating scanner is demonstrated to possess the capability of resolving 104 spectral bands and 250 spatial pixels. Delauney Triangulation is used in the signal processing to correct the spectral image distortions.
The paper presents an electrostatic in-plane rotational MEMS micro-scanner for circumferential scanned endoscopic optical coherence tomography probe. A diamond-turning-soft-lithography technology is introduced for six-slanted-facets pyramidal polygon micro-reflector fabrication.
MEMS optical scanners are highly desired due to their low-power, high-speed scanning. The in-plane vibratory grating scanner is a development in this area which possesses several unique features. The in-plane scanning minimizes the dynamic deformation, allowing for higher-resolution displays. The dispersive element permits splitting the incoming beam into its constituents for analysis and imaging...
A novel hyperspectral imaging application of the MEMS grating scanner is proposed in this paper. By utilizing the high-speed and optically dispersive characteristic of the grating scanner, a potentially low-cost, small footprint configuration is demonstrated. High-speed scanning without significant optical degradation due to dynamic deformation of the platform is possible using grating scanner. The...
This paper reports a broadband nondispersive optical phase modulation method using microelectromechanical systems (MEMS) technology. The proposed method utilizes in-plane translational motions of MEMS micro- grating elements to produce phase shifts in the diffracted light beams. The phase shift is dependent only on the ratio of the grating in-plane displacement to its period, and thus independent...
