Use of Supperresolution Apodizer to Increase the Focal Depth of HD-DVD
It is proposed that using a optimized three protion phase shifting apodizer to increase the depth of focus of the next generation digital versatile disk (DVD) and at the same time minimize the spot size. It makes the depth of focus of next generation DVD comparable to current DVD. The simulation result shows that an optical system with this apodizer also has a good defocus characteristic.
