Fast hyperspectral imaging using a mid-infrared tunable external cavity quantum cascade laser

Abstract

A hyperspectral imaging system using an external cavity quantum cascade laser and a focal plane array acquiring images at 25 Hz from 985 cm<sup>-1</sup> to 1075 cm<sup>-1</sup> with a resolution of 0.3 cm<sup>-1</sup> is demonstrated.
