External-cavity quantum cascade lasers (EC-QCL) are now established as versatile wavelength-tunable light sources for analytical spectroscopy in the mid-infrared (MIR) spectral range. We report on the realization of rapid broadband spectral tuning wi

We report on mid-IR spectroscopic measurements performed with rapidly tunable external cavity quantum cascade lasers (EC-QCLs). Fast wavelength tuning in the external cavity is realized by a microoptoelectromechanical systems (MOEMS) grating oscillat

In this work we present data analysis algorithms for detection of hazardous substances in hyperspectral observations acquired using active mid-infrared (MIR) backscattering spectroscopy. We present a novel background extraction algorithm based on the

We present spectroscopic measurements performed with an EC-QCL combining a broadly tunable quantum cascade laser chip with a tuning range of more than 300 cm-1 and a resonantly driven MOEMS scanner with an integrated diffraction grating for wavelengt

In this work we demonstrate standoff detection of traces of explosives using mid-infrared laser spectroscopy. We apply active laser illumination and use an infrared camera for collection of the diffusely backscattered laser radiation. The key compone

Investigators of linguistic devices such as minimal responses have assumed their function, neglecting to examine the matter empirically. This study introduces a technique enabling the identification of the function of such responses. With stereophoni

External-Cavity-Quantum Cascade Lasers are attractive sources for mid-infrared spectroscopy. We demonstrate the possibilities offered by EC-QCLs by two examples: Standoff detection of explosives and spectroscopic detection of contaminations in water
