Implication

Experimental evaluation demonstrates 3D imaging and material classification through camouflage beyond 40 meters, highlighting potential uses in military defense and robotic perception.

Key Points

To develop and experimentally evaluate Spectral LADAR, a system integrating 3D time-of-flight ranging with active shortwave infrared multispectral sensing.
Engineered a prototype active imaging system using a nanosecond-pulsed supercontinuum transmitter covering the 1080–1620 nm band.
Implemented a spectrally multiplexed receiver architecture to measure high-resolution range profiles across 25 individual spectral channels.
Demonstrated simultaneous 3D imaging and material identification at stand-off ranges exceeding 40 m.
Successfully revealed and classified material signatures of objects obscured behind camouflage using eye-safe infrared wavelengths.
