This instrument performs reflectivity measurements with -110 dB sensitivity and 80 dB dynamic range. The narrow linewidth allows long-range measurements, at 150 m, with a spatial resolution of 16 cm. At short range, about 5 m, the resolution increases to subcentimeter. Frequency modulation OFDR Tunable laser.
