Fluorescence Lidar

Remote detection of biological agents and contaminants is an INO specialty.

Over the years, we have developed laser-induced fluorescence (LIF) lidar systems for a variety of applications and customers, including National Defence Canada.

The fluorescence-based approach can be applied to solids, liquids, and gases to detect and identify substances with specific fluorescence bands.

Fluorescence lidar can scan 360° at ranges up to several kilometers and delivers immediate results with no sample preparation. No reagents or consumables are required for analyses. Moreover, intensified range-gated spectral detectors can reveal low quantities of contaminants and determine how they are distributed in space. Our technology is used primarily to detect:

  • Aerosol dispersion of bacteriological threats
  • Oil pipeline leaks and spills
  • Traces of narcotics and explosives in luggage
  • Gases possessing specific fluorescence bands

The technology also has applications in other areas:

  • Defense and security
  • Industrial hygiene
  • Oil industry
  • Mining
  • Aerospace
  • Environment
  • Cultural heritage

Our versatile systems enable clients to conduct measuring campaigns under real-life operating conditions so we can quickly determine whether a technology meets their requirements and better define their needs when designing a system.

Our highly sensitive method is also ideally suited to compact, low-power lasers. Emitting in the UV band, which is invisible to the naked eye, these lasers can be used to discreetly perform analyses without any risk of eye exposure. In addition, we design systems ranging in size from portable devices to trailer-mounted solutions, depending on client needs. Fluorescence and Raman technology can also be combined in the same system for maximal flexibility.
