Highly adaptable MEMS-based display with wide projection angle

We demonstrate a MEMS-based display system with a very wide projection angle°f up to 120°. The system utilizes a gimbal-less two-axis micromirror scanner for high-speed laser beam-steering in both axes. The°ptical scan angle°f the micromirrors is up to 16°°n each axis. A custom-designed fisheye lens is utilized to magnify scan angles. The system can display a variety°f vector graphics as well as multiframe animations at arbitrary refresh rates, up to the°verall bandwidth limit°f the MEMS device. It is also possible to operate the scanners in point-to-point scanning, resonant and/or rastering modes. The system is highly adaptable for projection°n a variety°f surfaces including projection°n specially coated transparent surfaces (Fig. 3.) The size°f the displayed area, refresh rate, display mode (vector graphic°r image raster,) and many°ther parameters are all adjustable by the user. The small size°f the MEMS devices and lens as well as the ultra-low power consumption°f the MEMS devices, in the milliwatt range, makes the°verall system highly portable and miniaturizable.
