The Fraunhofer Institute for Photonic Microsystems in Dresden, Germany, has developed a full-colour laser projection system based on its two-dimensional micro scanning mirror.
The projection system is suitable for a wide range of applications, including infotainment on mobile devices, such as PDAs and laptops, in the automotive industry for driver information systems, in medical electronics applications such as acquisition of biometric data, as a positioning aid in X-ray diagnosis and treatment, in engineering applications for the projection of reference points for drilling, or as a pattern generator for tailoring of steel plates.
The system consists of an ultra compact projection head and a separate laser and signal processing unit. It allows the projection of images and video sequences at a resolution of 640 x 480 pixels, 256 brightness levels per pixel and elementary colour, and a frame rate of 50 hertz.
The projection modules, developed by Fraunhofer IPMS in collaboration with the Fraunhofer Institute of Applied Optics and Precision Engineering, overcome limitations of conventional projection systems, such as the large components needed for light deflection and the use of high power light sources that use lots of electrical power and radiate most of it thermally, by using a micro scanning mirror for image generation and lasers as light sources.
The projector system will be on show at Laser 2007 in Munch, 18 – 21 June.
