Quartz tuning fork as photodetector for benzene monitoring beyond 12 μm

European Conferences on Biomedical Optics 2025
A novel sensor for detecting BTEX compounds was developed using light-induced thermoelastic absorption spectroscopy (LITES). The system employed an InAs/AlSb quantum cascade laser (14.85 µm) and a custom quartz tuning fork photodetector, with benzene selected as case study.
