High-speed scanless entire bandwidth mid-infrared chemical imaging.

Abstract in brief

• The article describes a new method for high-speed, wide-bandwidth midinfrared chemical imaging that uses chirped pulse upconversion to achieve detailed and rapid spectral analysis of molecular vibrations, enabling identification of chemical species and functional groups.
• This technique provides a high spatial resolution of 15 micrometers, a large adjustable field of view, and can produce detailed hyperspectral images (640x480 pixels) in just 8 seconds, covering over a thousand wavelengths with fine spectral resolution.
• Demonstrations include mapping components inside microfluidic devices, plant cells, and mouse embryos, showcasing its potential applications in fields like chemistry, biology, and medicine due to its speed, accuracy, and broad spectral range.]
