Flexible design, high light efficiency and high contrast. The theoretical picture can reach infinity without focusing. The single micro mirror in Longma Puxin MEMS scanning chip can vibrate at high speed in two directions perpendicular to each other (in Microsoft hololens, the micro mirror is a combination of two uniaxial micro mirrors, and each micro mirror can only vibrate in one direction, so the structure is complex). The modulated laser carrying image information is shot onto the mirror, which is scanned and projected by the lens. It has flexible design, high optical efficiency and high contrast. The theoretical picture can reach infinity without focusing. The impact, vibration and temperature performance of the lens meet the requirements of vehicle regulations, the mean time between failures (MTBF) exceeds 60000 hours, and the mass production process is stable.
