Alex Hegyi is working on a new invention that aims to make hyperspectral imaging (HSI) an ubiquitous technology, whereby a full optical spectrum is sampled at each point in an image. Dr. Hegyi’s invention has the potential to radically simplify HSI technology, enabling HSI systems that add minimal cost and bulk to existing camera sensors without sacrificing software adaptability to specific applications, and with potential impact to fields as diverse as medicine, agriculture, security, defense, and even cosmetics. Dr. Hegyi’s expertise is broadly in the realm of optical detection systems; he also invented and leads development of PARC’s highly multiplexed wavelength shift detector for readout of fiber optic sensor arrays, and he contributes to PARC’s efforts in flow cytometry.
Previously to his time at PARC, Dr. Hegyi independently invented and developed a novel medical imaging concept called nanodiamond imaging. Nanodiamond imaging is a kind of functional biomedical imaging (like PET or SPECT) that uses biologically-tagged nanodiamonds containing nitrogen-vacancy centers as a contrast agent. By taking advantage of optically-detected magnetic resonance of the nitrogen-vacancy centers, nanodiamond imaging has the potential to image with a combination of high spatial resolution and high sensitivity, features that are incompatible in existing imaging modalities except at the shallowest imaging depths. For his thesis, Alex built and demonstrated two imaging systems and performed the first imaging within scattering tissue using optically-detected magnetic resonance.
Dr. Hegyi graduated in 2013 with a Ph.D. in Electrical Engineering and Computer Sciences from the University of California, Berkeley, where he was advised by Prof. Eli Yablonovitch and fully supported by a P. Michael Farmwald Fannie and John Hertz Foundation Fellowship. He received his B.S. with Honors and Distinction in Physics from Stanford University in 2008. He holds 12 patents from work performed prior to PARC and has many more pending.
