Abstract

We present a new full-custom instrument for time-domain diffuse optical spectroscopy developed within Horizon 2020 LUCA (Laser and Ultrasound Co-Analyzer for thyroid nodules) project. It features eight different picosecond diode lasers (in the 635 - 1050 nm range), two 1.3 × 1.3 mm² active-area SiPMs (Silicon PhotoMultipliers) working in single-photon mode and two 10 ps resolution time-to-digital converters. A custom FPGA-based control board manages the instrument and communicates with an external computer via USB connection. The instrument proved state-of-the-art performance: an instrument response function narrower than 160 ps (fullwidth at half-maximum), a long-term measurement stability better than 1%, and an output average optical power higher than 1 mW at 40 MHz. The instrument has been validated with phantom measurements.
