Innovative Spectroscopy and Hyperspectral Imaging Systems Based on a Common-Path Birefringent Interferometer (F1A.1)
Presenter: Dario Polli, Politecnico di Milano

We present a compact, ultra-stable common-path birefringent interferometer for Fourier-transform spectroscopy that provides several advantages with respect to standard amplitude-division interferometers. We illustrate a very broad portfolio of experimental applications from time-resolved fluorescence spectroscopy to non-linear (pump-probe, two-dimensional and coherent Raman) spectroscopy, from hyperspectral imaging for remote sensing to microscopy for biological applications.

Monolithic Micro Spectrometer to Determine Best Time to Harvest Fruits (F1A.2)
Presenter: Sven Schönfelder, INSION GmbH

Monolithic micro spectrometers do not require recalibration and, due to their miniaturized and rugged design, they are ideally suited for hand-held devices and field measurements. Most of the annual apple harvest is stored in special warehouses for several months. By means of micro spectrometer-based sensors, the harvest time can be optimally determined in the field in order to avoid internal pulp discolorations in the shelf life and trading periods of the products.

Development of Fast Frequency Comb Mid-Infrared Spectroscopy for Stopped Flow Applications (F1A.3)
Presenter: Raphael Horvath, IRsweep

Dual frequency comb spectroscopy is used to address limitations of stopped flow infrared spectroscopy, namely, speed, resolution, and the need to repeat reactions to obtain good signal to noise ratios at short timescales.
