MIR Upconversion Imaging Could Speed Medical Diagnostics
LYNGBY, Denmark, June 4, 2019 — Researchers from multiple institutions collaborated to develop a way to translate information from the mid-infrared (MIR) region, where chemical signatures are most distinct, to the near-infrared (NIR), where existing camera technology is most sensitive. The wide field-of-view system can support upconversion of monochromatic MIR images for hyperspectral imaging (HSI). The technology could be used to look for the chemical signatures of cancer and other diseases in ways that would increase
