Abstract: Optical imaging is a powerful tool that has found widespread use in vast areas of science and industry. Fluorescent imaging is an indispensable component of many biological investigations, owing to the ability to track specific molecules. Coherent nonlinear optical imaging, based on inelastic nonlinear light scattering driven by intense laser fields, provides contrast mechanisms that provide information not accessible by other optical imaging methods. Nonlinear optical imaging is particularly useful in complex environments that suffer from significant optical scattering and absorption where conventional camera-based methods fail. Optical imaging with single pixel detection enables imaging detailed structures in specimens by scanning a point focus of light in three dimensions. I will discuss recent advances in multiplexed imaging where dynamically structured illumination light is able to extract significantly more spectroscopic and spatial information from a specimen. Application of dynamic light structuring to classical super resolution microscopy, hyperspectral imaging, and Raman microscopy, a new form of coherent nonlinear tomographic imaging will be reviewed. The talk will focus on the exploitation of quantum correlations for improved super resolution imaging and computational fusion imaging.
