Abstract
The present invention provides a projecting apparatus. The projecting apparatus comprises: a light source, a lens, and a diffractive optical element (DOE). The light source is utilized for emitting a Gaussian beam. The lens has a focal length, and is utilized for receiving the Gaussian beam and generating a de-focused Gaussian beam, wherein a distance between the light source and the lens is not equal to the focal length. The DOE is designed for the de-focused Gaussian beam, and utilized for receiving the de-focused Gaussian beam and spreading out a non-diffracted light of the de-focused Gaussian beam.
