Hyperspectral Imaging Applications in Art and Forensics

Advanced Applications in Forensics: Non-Invasive Evidence Analysis

Hyperspectral imaging offers forensic scientists a unique advantage in analyzing evidence, documents, and artifacts non-invasively. This advanced technology enables forensic teams to thoroughly evaluate crime scene evidence, highlighting the distinct characteristics of each sample. Hyperspectral imaging also plays a critical role in identifying counterfeit documents and goods, revealing details that may appear genuine to the naked eye but stand out under hyperspectral analysis.

Spectral Imaging for Cultural Heritage: Rapid, Non-Destructive Analysis

For cultural heritage, hyperspectral imaging in the infrared range has transformed the way artifacts are analyzed and preserved. This technique provides rapid, non-contact analysis across hundreds of narrow spectral bands, collecting comprehensive data without damaging fragile items. For instance, hyperspectral imaging can reveal past repairs that are invisible to the eye, as shown by chemical imaging of a restored vase, where the restoration is distinct from the original material (see application note).

Historic Document Analysis: Enhancing Accuracy and Authenticity

Hyperspectral imaging has proven invaluable for analyzing historic documents like the Dead Sea Scrolls, the Gettysburg Address, and ancient maps. This technology enhances faded or hidden features, verifies authenticity, and identifies areas needing restoration, providing a non-invasive way to safeguard cultural heritage.
