Improved logarithmic phase mask to extend the depth of field of an incoherent imaging system

A logarithmic phase mask was proposed in 2001, and the depth extension effect was proved at the same time. Three years later, in 2004, further research on that kind of mask obtained more results. This valuable work can be found in two papers [Proc. SPIE 4471, 272 (2001) and Appl. Opt. 43, 2709 (2004...
