NIR Capturing images with spectral information in the mid-infrared

We demonstrate a method to capture images containing spectral information in the infrared. The method is based on sum frequency mixing of light, which allows for transformation of mid-infrared radiation to near visible light, allowing for use of a regular silicon based camera for detection. Combined, this leads to much improved sensitivity over existing methods for infrared imaging.

The principle is generic and can be applied towards a multitude of different applications.
