Russia develops a laser-based “listening” system for utility pipelines

Russia has introduced a breakthrough optical technology that remotely “listens” to water and heating infrastructure using colored lasers and holographic patterns. By detecting microscopic vibration changes in pipes and pump systems, the method offers instant diagnostics that can prevent leaks, blockages, and equipment failures—marking a significant leap in the digital transformation of public utilities.

Normal Hum — and Abnormal Vibrations

Every pumping or liquid‑transport system produces a characteristic vibration signature. When equipment operates properly, this signature stays within a predictable range. Any deviation is an early indicator of malfunction.

Unlike existing electronic sensors that require physical installation and often cover only narrow frequency bands, the new Russian system relies on an optical method. Several colored laser beams interact with a specialized film, producing a dynamic holographic image. The pattern instantly reflects changes in vibration intensity across different frequency ranges.

Researchers from Tomsk State University of Architecture and Building, working with Sevastopol State University, highlight that the system’s power lies in its mix of precision, speed, and potential affordability.

“A multicolored image is streamed to a computer with the processing power of an ordinary modern laptop,” explains Andrey Mostovshchikov, Director of the Research Institute of Building Materials at Tomsk University. “If one color begins to dominate, it means vibration in that range has intensified—signaling that a component of the pumping infrastructure needs closer attention.”

A System Without Weak Spots

The optical diagnostic method does not suffer from the limitations typical of electronic sensors. It does not require complex, expensive installation procedures, has no narrow sensitivity range, and operates in real time—a critical advantage for preventing major utility accidents.

Deploying such technology in Russia’s municipal sector can significantly reduce resource losses, minimize the probability of large‑scale infrastructure failures, and ultimately improve the reliability of water and heat supply for residents.

This Russian innovation offers a highly effective tool for evaluating wear and tear in public utility systems—one with strong potential for global adoption.

“Two of our industry partners are already prepared for practical cooperation and pilot‑scale testing,” notes Oleg Volokitin, Vice‑Rector for Research at the Tomsk university. “This is the very ‘transition point’ we work toward—when a scientific idea becomes a real‑sector product or technology.”

Next Step: Harsh Industrial Environments

The upcoming phase involves trials in demanding industrial settings, where dust, steam, and fluctuating temperatures can complicate diagnostics. Successful results will pave the way for full‑scale implementation of this laser‑based monitoring system across the utilities sector.
