Optical Advantages of Curved Image Sensor

This old paper becomes more interesting in light of the recent curved sensor developments. In March 2008, Optics Express published a paper "The optical advantages of curved focal plane arrays" by Staford University team of Seung-Bum Rim, Peter Catrysse, Rostam Dinyari, Kevin Huang, and Peter Peumans:

"...we have shown that a curved imager provides a large degree of freedom in the design of the camera system, helps reduce fundamental aberrations and provides better resolution and brightness. This was demonstrated using designs for a simple and compact camera system by a full analysis of the characteristics of digital imaging systems with planar and curved FPAs."
