Mid-IR standoff measurement of ageing-related spectroscopic changes in bitumen in the 6 µm (1700 cm−1) region. Part 1: Measurement strategy and instrument design principles
Laser modulation and demodulation
It was decided to detect modulated signals from each laser, in order to reject changes in ambient light levels and to enable separation of signals from each of the 4 lasers while using a single photodetector. Each…
