摘要： Disclosed are a system and method for microprojection that uses multiple imagers to produce a high resolution output image. Each of a set of imagers produces a portion of the final image. Relay lenses then tile the individual image portions together into a combined image. Because the height of the individual imagers is smaller than the height of a monolithic imager, they can fit into a very thin device. The combined image has a resolution equal to the sum of the resolutions of the individual imagers. The individual images are tiled together within the microprojector itself rather than on a projection screen. This allows the tiling to be adjusted once at the factory and set forever. In some embodiments, the light created for use by the microprojector is split by a polarizing beamsplitter. Each resultant polarized beam is then sent to an imager. Another polarizing beamsplitter combines the individual images.

摘要： Disclosed are a system and method for microprojection that uses a “reduced-height” imager to sequentially display a series of partial images within one frame time. The partial images visually combine on a projection surface (e.g., a screen or a wall) into one high-resolution projected image. As a result, the microprojector projects an image with a resolution equal to the sum of the resolutions of the individual partial images while avoiding the use of very small imager optics with their lowered efficiency. For example, one embodiment projects exactly two partial images during each frame. During a first state of operation, a “half-height” imager displays the odd-numbered lines of the projected image. During a second state of operation, the imager displays the even-numbered lines of the projected image. By quickly cycling through these two states, no image flickering between phases is visible, and the combined image appears as a seamless whole.

摘要： A method and apparatus that projects a two-dimensional image is disclosed. The method may include emitting a laser beam, sweeping the laser beam with a first scan mirror along a first scan direction to form a scan line on the projection surface, and sweeping the scan line with a second scan mirror along a second scan direction generally orthogonal to the first scan direction to form a raster pattern of scan lines on the projection surface. The scanner for the first scan mirror is driven with a stimulus waveform, wherein the stimulus waveform has a fundamental frequency that is substantially equal to the resonance frequency of the scanner but also contains harmonics to achieve a nearly constant velocity of the laser beam spot during its scan across the projection surface. The stimulus thereby reduces peak laser output power and corresponding noise generation while maintaining image brightness and image quality.

摘要： A gravity gradiometer having at least three differential accelerometers with a low response to linear accelerations and at least six angular accelerometers that give it the capability of measuring angular rates by integrating the angular accelerations. Both types of accelerometers are based on a compliant mechanism with very low and adjustable stiffness that is achieved by using flexures under compressive load that contribute a negative stiffness to the total elastic response of the mechanism. Both types of accelerometers are operated in a servo-compensation feedback mode so that at no time is the mechanism far from its equilibrium position.
