Sony - Focus-Free High-Resolution Pico Projector Module
Sony has announced the development of an extremely sophisticated small-size projector module (Pico Projector Module), that can be used to project images from smart devices such as smartphones or tablets.
It uses an image processing system, independently-developed by Sony, that uses laser beam scanning (LBS) to create crisp, high-definition and "focus-free" projection regardless of distance, angle or projection surface.
The LBS uses a semiconductor laser as its light source, the laser beam is then reflected and controlled using an MEMS (Micro Electro Mechanical Systems) mirror to scan and project the image. It uses a video processor to control the video signal processing and image output.
By developing a video processor that precisely controls the semiconductor laser and MEMS mirror, Sony has achieved high-resolution HD image quality that surpasses VFA and WVGA, which are the current mainstream resolution for battery-driven pico projectors.
Resolution with this module is 1920 x 720 with aspect ratio 16:9. (Currently, modules mounted on battery-driven pico projectors use a panel system, which generally have VGA (640 x 480) or WVGA (800 x 480) resolution.)
This model can project clear 40-inch images from a distance of 1 meter and 120-inch images from a distance of 3 meters. Also, the optical technology in the projector has achieved a significant reduction in laser speckle noise, which had previously been a challenge for LBS systems.
Perhaps the most interesting feature is that the light-harvesting capability and directness of the laser beam ensure that the projected image remains in focus, regardless of the distance or angle from the projection surface.
