In upconversion imaging phase matching severely limits the spectral bandwidth, therefore requires serial acquisitions to cover a large spectrum. Researchers in Israel have designed an upconversion imaging scheme covering the mid‐IR based on adiabatic frequency conversion. They presented mid‐IR multicolor imaging and demonstrated simultaneous imaging on a CMOS camera of radiation spanning a spectrum from 2 to 4 µm. This approach being coherent and ultrafast in essence, spectrally resolved spatiotemporal imaging is further demonstrated that allows spatially distinguishing the temporal evolution of spectral components. The findings has applications in a variety of fields from computer gaming and photography as well as the disciplines of security, medicine, and astronomy…read more. TECHNICAL ARTICLE
