Abstract
Spectral imaging in the mid-infrared (MIR) range provides simultaneous morphological and chemical information of a wide variety of samples. However, current MIR technologies struggle to produce high-definition images over a broad spectral range at acquisition rates that are compatible with real-time processes. We present a novel spectral imaging technique based on non-degenerate two-photon absorption of temporally chirped optical MIR pulses. This new approach avoids complex image processing or reconstruction and enables high-speed acquisition of spectral data cubes [xyw] at high pixel density in under a second.
