A new article in CU Boulder Today highlights a recent paper published in a special issue of Optics & Photonics News called Optics in 2023 when JILA Fellows and University of Colorado Professors Margaret Murnane and Henry Kapteyn and their groups use ultraprecise light to image nanosurfaces. 

"The research is the latest advance in the field of ptychography, a difficult to pronounce (the “p” is silent) but powerful technique for viewing very small things," the article states. "Unlike traditional microscopes, ptychography tools don’t directly view small objects. Instead, they shine lasers at a target, then measure how the light scatters away—a bit like the microscopic equivalent of making shadow puppets on a wall."
