14th Edition of Forensic Scientist Awards 26-27 September 2025 | Mumbai, India
🚔 Why It Matters
One of the biggest challenges for crime scene investigators is the rapid detection of evidence without disturbing the site. In the first few minutes, investigators need to quickly identify key forensic elements such as blood, drugs, or explosives while minimizing exposure to hazardous substances. Traditional methods often involve time-consuming sample collection and lab analysis, which can delay the investigation.
This is where infrared (IR) standoff spectroscopy comes in as a game-changer.
🔎 What’s New?
A team of researchers has developed and evaluated a prototype IR standoff spectrometer specifically for rapid forensic surveying at crime scenes.
-
Technology Principle: Diffuse-reflectance spectroscopy in the mid-infrared region.
-
How It Works: Two multiplexed IR lasers illuminate the target from a distance of up to 1.5 meters, and the reflected spectra are analyzed in real time.
-
Speed: Millisecond-resolution, uninterrupted measurements.
This means investigators can detect and classify suspicious materials instantly — without needing to physically handle them at the scene
⚡ Tested Substances
The prototype was evaluated on a wide range of forensic-relevant substances, including:
-
Blood
-
Explosives
-
Drugs of abuse
-
Precursors & adulterants
-
Cutting and bulking agents
✅ Key Findings
-
High detection accuracy for most tested samples.
-
Strong selectivity in distinguishing blood from interferents — a critical factor in early-stage crime scene processing.
-
Safe & non-invasive detection, reducing risk from hazardous exposure.
🌍 Why This Matters for the Future of Forensics
This innovation has the potential to redefine crime scene investigations by:
-
Reducing investigation time
-
Prioritizing evidence collection
-
Enhancing safety for forensic teams
-
Supporting real-time decision making
As forensic science moves toward more field-deployable, AI-assisted technologies, IR standoff spectrometers could become standard tools for rapid, reliable, and safe surveying of crime scenes.
