Abstract
Our Computer Generated Holograms are made of different thin stripes, each of them modifying the phase of the input scanning beam. There are two main set-ups. If the size of the stripe is equal to or larger than the scanning beam, we can address the different points or modify the phase pattern of the scanning beam in a discontinuous way. But if the size of the stripe is much smaller than the scanning beam, we will almost get a continuous variation of the phase pattern as the beam changes its position. With this, we can modify the input wavefront either into a smooth curve or corrected beam.
