Abstract

Image processing has become a critical technology in a variety of science and engineering disciplines. While most image processing is performed digitally, optical analog processing has the advantages of being low-power and high-speed though it requires a large volume. Meta-optics provide the advantage of thin form factor optics while also allowing complex transfer functions to be employed. In this talk, I will discuss the use of meta-optics for applications in image processing. Specifically, I will discuss meta-optic pre-filters including edge filters as well as filters for identifying higher level spatial features. These meta-optics are designed in conjunction with the digital system and I will discuss how co-design can make the hybrid optical / digital system more tolerant to deterministic and stochastic noise. These analog optical operations can be used to replace, or augment, digital processes for increasing speed while reducing power consumption.
