One can gain a great deal of physical and chemical insight from images and likewise one can apply mathematical and physical intuition towards the design of better imaging systems. In the first part of my talk I will discuss our lab's research focus on imaging, manipulation, and spectroscopy at the nanoscale.  We employ scanning tunneling microscopy to investigate the electronic and chemical properties of a wide-range of materials including graphene, organic semiconductors, and macroscale-inspired molecular machines. The latter two thirds of my talk will focus on the new field of compressive imaging, spotlighting its implementation in infrared, hyperspectral, and a sum-frequency generation microscope system. The basis of these systems is that one can exploit sparsity when acquiring signals and that one can condense the information during acquisition using far fewer samples than previously believed. The last part of this talk will highlight how we address the challenges of acquiring video in such imaging systems given that a large focal plane array is replaced by many measurements in time with a single detector.
