A head-up display includes an image source, such as a laser scanner, a means
for
diffusing light and a transparent element that can include a holographic element.
The laser scanner emits a visible light for generating an image. The means for
diffusing light receives the visible light from the laser scanner to project the
image thereon, and preferably apply gain thereto. The transparent element produces
a virtual or a real image of the image from the means for diffusing light. In a
vehicle, the head-up display is configured to reflect the image into the vehicle
to provide a virtual image ahead of a driver.
