A next-generation reconfigurable photonic platform that is compact, versatile, and suitable for a wide range of spectroscopic modalities, including reflection, absorption, colorimetry, and fluorescence with single or multi-wavelength excitation. The prototype features a pocket-sized 3D-printed enclosure integrating a circular array of 12 LEDs, with wavelengths customized to the target application, and a miniaturized spectrometer positioned at the center of the array to act as the detector.

The instrumentation is based on the electrical resistivity tomography (ERT) which is a non-invasive geophysical technology used to obtain information on anomalous bodies possibly present in the subsoil. The theoretical basis lies in the different electrical properties of the lithotypes present in the subsoil.
