Imaging systems are now complex instruments where lens, sensor and digital processing interact strongly together. In order to obtain better imaging performance than conventional imaging, it has become necessary to take into account this interaction in the design stage and therefore to optimize jointly optical and digital parameters. The objective of my thesis is to develop joint optical-digital optimization methods in order to obtain imaging systems with higher performance and lower complexity. I first considered extending the depth of field of an already existing lens. A binary phase mask has been inserted in the vicinity of the aperture stop of a f/1.2 lens, and it has been optimized jointly with a deconvolution filter using the restored ...
