PicoLAS GmbH, based in Würselen near Aachen, has been developing compact systems for controlling laser diodes for many years; these systems are used primarily in industry, medical technology, and scientific applications. The focus is on high precision, reliability, and efficiency while minimizing space requirements. At INTERSCHUTZ 2026 in Hanover, PicoLAS will present its technology in the context of modern hazard prevention.

Drone-Based Hazardous Substance Analysis in Action

When emergency responders are dispatched to fires or hazardous material incidents, a quick and reliable assessment of the situation is crucial. Unknown hazardous substances can pose significant risks to both the public and emergency responders. Modern drone systems have so far made it possible to survey contaminated areas from a safe distance. Now, as part of the “SiSchaMo” (Safe Hazardous Substance Monitoring via UAS) research project, a flight-capable, multimodal sensor platform has been developed that detects hazardous substances directly in the field. The precise electronics and laser technology from PicoLAS plays a central role in this.

Technology for Accurate Measurement Results

Many of the sensors used are based on optical measurement methods. Laser light is used to uniquely identify chemical substances based on their specific absorption or scattering. For these methods to function reliably, extremely precise control is required. PicoLAS develops specialized laser drivers and electronic components for this purpose, enabling stable and energy-efficient operation. These characteristics are particularly crucial for use in drones: The systems must be lightweight to ensure long flight times, operate efficiently, and deliver high measurement accuracy even under changing environmental conditions.

Modular System for Flexible Applications

The sensor platform used in the project follows a modular approach. Depending on the application scenario, different sensors can be integrated. These include, among others, gas sensors based on NDIR technology, optical particle counters for measuring fine dust, and sensors for detecting radioactive radiation. A central data module records all measured values at short intervals and reliably transmits them to a ground station. This is done either via LoRaWAN or via a mesh network in the 2.4 GHz band, ensuring stable communication even over long distances.

Real-time data for better decisions

The collected data is consolidated in specialized software and visualized in real time. This provides emergency responders with a three-dimensional representation of hazardous substance distribution, allowing them to immediately identify contaminated areas. Color-coded zones facilitate rapid assessment of the situation and support informed on-site decision-making.

With this combination of compact electronics and powerful photonics, PicoLAS helps increase safety during operations and significantly improve the assessment of hazardous material situations. Visitors to INTERSCHUTZ 2026 can see these developments firsthand and learn about the capabilities of modern sensor technology in emergency response.
