The authors present a fast mid-infrared hyperspectral chemical imaging technique that uses chirped pulse upconversion of sub-cycle pulses at the image plane, with lateral resolution of 15 µm and an adjustable field of view and large spectral range. They demonstrate identification and mapping different components in a microfluidic device, plant cell, and mouse embryo.
