A 10-nm Spectral Resolution Hyperspectral LiDAR System Based on an Acousto-Optic Tunable Filter

Sensors, 2019
Hyperspectral LiDAR (HSL) technology can obtain spectral and ranging information from targets by processing the recorded waveforms and measuring the time of flight (ToF). With the development of the supercontinuum laser (SCL), it is technically easier to

RAMAN SPECTROSCOPIC MEASUREMENTS OF CO2 DISSOLVED IN SEAWATER FOR LASER REMOTE SENSING IN WATER

, 2016
We examined the applicability of Raman lidar technique as a laser remote sensing tool in water. The Raman technique has already been used successfully for measurements of CO 2 gas dissolved in water and bubbles. Here, the effect of seawater on CO 2 Raman
