Colloquium Marta Fajardo
Today from 16:00 to 17:00 in EA5 Room at Mechanics Building I, Marta Fajardo will present a Colloquium about NanoXCAN: Seeing the Invisible with Light and Noise.
Abstract:
What if we could image a single virus—not in a large international facility, but on a tabletop, using only light and clever physics? NanoXCAN is building a new kind of X-ray microscope to do just that. At its heart is a next-generation digital laser, capable of sculpting intense light pulses with precision far beyond traditional optics. When this light hits a nanoscale target, it generates hard X-rays bright enough to probe structures a thousand times smaller than a grain of sand.
But here's the twist: we don't use lenses. Instead, we let the quantum nature of light do the work—capturing noisy, scattered photons and using statistical correlations and machine learning to make images emerge from the chaos. It's a new approach to seeing, one where physics replaces optics. In the process, we aim to bring capabilities once reserved for synchrotrons into regular labs like our own—and maybe, one day, even hospitals.
All are invited to attend
