Abstract
This talk will discuss two of the new imaging system under development by QuantIC, the UK’s center for research in Quantum Inspired Imaging. The first of these systems use correlated pairs of photons produced by parametric down conversation as the probe and reference channels in an imaging system. Our goal is to eliminate sources of background light and sensor noise from images. Using commercially available sources and cameras we are able to eliminate ≈95% of this background light/noise hopefully creating a new modality of low light imaging.
The second of these systems is an endoscopic imaging system the width of a human hair. This endoscope is based upon a single multi-mode optical fiber and uses used light, not only to create an image of the scene but through photon, timing can recover depth information to image in 3D. Using high-speed beam shaping techniques we are able to recover images with a resolution of 50×50, a depth accuracy 5Hz.
Miles Padgett is a Royal Society Research Professor and also holds the Kelvin Chair of Natural Philosophy at the University of Glasgow. He leads an optics research team covering a wide spectrum from blue-sky research to applied commercial development, funded by a combination of government, charity, and industry.
His research team covers all things optical from the basic ways in which light behaves as it pushes and twists the world around us, to the application of new optical techniques in imaging and sensing systems. They are currently using the classical and quantum properties of light to explore: the laws of quantum physics in accelerating frames, microscopes that see-through noise, shaped light that overcomes diffraction-limited resolution, endoscopes the width of a human hair, and new ways of imaging in 3D. He has won a number of national and international prizes including, in 2019, the Rumford Medal of the Royal Society. The team’s papers and article-level metrics are found here. He is currently the Principal Investigator of QuantIC, the UK’s Centre of excellence for research, development, and innovation in quantum-enhanced imaging, bringing together eight Universities with more than 40 industry partners.
