Lasers are an interesting option as a light source§for projection displays, because of their high§directivity. As a result, a high brightness light§source with a small beam profile, a good beam quality§and good collimation characteristics is obtained.§This allows the application of small light engines§and display panels without loosing much intensity. As§a result, a small and quite cheap projector can be§gained. If the panel costs are still too high, laser§sources can also be used to realize even cheaper§architectures that use 1D display modules or a flying§spot scanner. Additionally, the laser beam is highly§monochromatic, so a projection unit using three§primaries can cover a large colour gamut. §The intention of this book is to give an overview on§state of the art projection techniques, applicable§laser sources and challenges in setting up micro- or§even high power laser front projection systems.
