Abstract: The basic design of the camera — a lens and an imaging sensor — has remain unchanged for many centuries. While this design has been perfected for professional photography, there are many current and upcoming application domains where it is woefully inadequate. I will discuss three such examples: high-resolution imaging in infrared, extremely thin form-factor cameras, and post-process freedom. In each example, I will discuss research from my work on novel imaging designs and associated image processing techniques that provide capabilities that far exceed those of the conventional design. Central to the talk is the idea of computational imaging, the co-design of optics and processing to break the limitations of conventional imaging designs.
