Lasers are an interesting option as a light sourcefor projection displays, because of their highdirectivity. As a result, a high brightness lightsource with a small beam profile, a good beam qualityand good collimation characteristics is obtained.This allows the application of small light enginesand display panels without loosing much intensity. Asa result, a small and quite cheap projector can begained.

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.
