Penetration and scattering-Two optical phenomena to consider when applying proximal remote sensing technologies to...

Area of Science:

• Optics
• Remote Sensing
• Spectroscopy

Background:

• Proximal remote sensing is widely used across disciplines, often by non-experts in optical physics.
• Understanding optical phenomena is crucial for reliable data acquisition and interpretation.

Purpose of the Study:

• To investigate the influence of optical penetration and scattering on the robustness of proximal remote sensing data.
• To evaluate how these phenomena affect hyperspectral reflectance measurements.

Main Methods:

• Laboratory experiments were conducted to analyze optical penetration and scattering.
• Hyperspectral reflectance data were collected across 40 spectral bands (385-1024 nm).
• Robustness was assessed based on data repeatability and object distinguishability.

Main Results:

• Both optical penetration and scattering significantly impacted the robustness of hyperspectral reflectance data.
• The influence of these optical phenomena varied across the examined spectral range.
• Penetration affects signals from surface and internal properties, while scattering involves external influences.

Conclusions:

• Characterizing optical phenomena is essential for improving the quality and reliability of proximal remote sensing.
• This understanding is vital for accurate classification of engineering and biological objects using remote sensing technologies.
