Researchers have developed a unique high-resolution imaging method that can capture mid-infrared spectral images of fast events or dynamic processes that take place on the order of milliseconds. This spectral range is used for many applications because it can reveal the detailed chemical composition of a sample.
“This novel approach could one day be used to prescreen medical biopsies to identify the ones that need closer examination,” said Peter Tidemand-Lichtenberg, a member of the research team from DTU Fotonik in Denmark. “It could be used to look for the chemical signatures of cancer and other diseases in ways that would increase the accuracy and speed of diagnoses.”
A multi-institutional group of researchers describe the new imaging approach in Optica, The Optical Society’s (OSA) journal for high-impact research. They also demonstrate some of the technique’s potential applications by imaging a gas flow and distinguishing cancerous and normal samples of esophageal tissue.
