Integral imaging with increased depth of field and depth of focus by using phase masks

摘要

Integral imaging systems permit to capture and reproduce three-dimensional scenes. However they usually suffer from a limited depth of field and/or limited depth of focus that severely reduces the depth range that can be used in practice. In order for such a system to be able to capture and reproduce large-depth scenes without any adjustment, we propose to include in the integral imaging system an array of phase masks in order to increase the depth of focus of the final three-dimensional images. We consider both the pickup and the reconstruction stages.
