And what would that do? Having such a focal surface that can conform to the scene geometry allows you to have any type of focusing across the sensor you have. For example, you can perform optical all-in-focus imaging, which has been studied extensively in the literature. But the two most straightforward ways to obtain all the stuff in focus, one is to use small aperture, meaning that you decrease the size of the aperture. Your depth of field increases, so you can have more depth in focus. But then that also comes with light loss. The smaller the aperture you use, the less light you have. And also the smaller the aperture you use, the more diffraction blur you encounter. 5 DAILY ICCV Thursday Yingsi Qin
