ABSTRACT:
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.
