Abstract

In this work we present an alternative to sonar based underwater mine countermeasures (MCM) using an active optical system based on light detection
and ranging (LiDAR) sensor. Multi-spectral (MS) full-waveform (FW) single photon (SPC) data is analysed for material and structural discrimination.
Terrestrial and aerial LiDAR has enabled researchers to explore the third
dimension, depth; this has advantages in bathymetric mapping [2] and defence and security [1]. Commercial and academic focus [2] on bathymetric
LiDAR has only been on shallow waters and uses either monochromatic
laser sources or a maximum of two wavelengths. This work is the first to
report signal analysis for foliage penetration and discrimination of underwater LiDAR data. The multi-spectral depth imaging system [4] used in this
study is based on the time-of-flight (ToF) approach using time-correlated
single photon counting (TCSPC). The TCSPC module (Hydraharp in Figure 2) time-stamps each photon event reflecting from a target and records it
using a single-photon detector. The photon counts can then be time gated to
form a histogram, a full-waveform, whose inherent nature depends on several factors, e.g., the laser wavelength, surface geometry and transmission
medium.
