STABO-Tech is an Authorised Promoter of
innovative Tuneable Diode Lidar (TDLidar) quantum systems addressed to detection and 3D imaging  of gaseous compounds.
This system, named QLM Quantum Camera is particlarly useful for detection of methane (CH4) leaks. The infrared single-photon detection is implemented in rang-resolving mode, allowing not only to individiate the leaks of CH4, over extended industrial or agriculture areas,  bit also to quantify them. All these performaces of the QLM QuantumCamera provide the possibility to reconstruct the 3D distribution of the CH4 leaks. The camera is designed to operate in 24/7 mode, providing  low-cost valuable information for quantifying of CH4 leak identification and operational information for timely remediation.

A way to monitor for emissions that:
  • Is continuous/real time (24/7, day/night/weather)
  • Is on site (small, low power,autonomous)
  • Is widely deployable (low cost)
  • Can localize/pinpoint/visualize individual emission sources
  • Can quantify individual emission sources
  • Increases the return on leak detection and remediation cost (analysis, prioritization)


CH4 is oane of the key greenhose gases. The atmospheric content of CH4  is a subject of a particulary interest caused by its high Global Warminp Potential (GWP).
Large quantities of CH4 are emitted from biomethane and biogas supply chains, including digestate handling, anaerobic digesters, upgrading units, raw material storage and transmission, and storage and distribution stages. CH4 is a relatively short-lived greenhouse gas, but it has GWP 28 times greater than CO2 over a 100-year time horizon and 84 times greater over a timescale of 20 years*.
It's considered that the reduction of CH4 emissions by antropogenic activity can play as one of the most immediate and effective mitigation strategies to limit global warming in the short term.
Without objective and contunuos monitoring of the CH4 leaks can't be assesed the efectivnees of the actions implemented to minimise the negative effects caused by climate cange.  QLM Quantum Camera is the right solution for such monitoring.

Operational principe of QLM Quantum Camera

The QLM Quantum Camera uses a new technique called Tunable Diode Lidar (TDLidar) which combines aspects of Tunable Diode Laser Absorption Spectroscopy (TDLAS) with Differential Absorption Lidar (DIAL) and Time Correlated Single Photon Counting (TCSPC) to enable remote spectroscopy and ranging with low power semiconductor diode lasers. The first TDLidar methane sensors use diode lasers with wavelengths around the CH4 absorption line at 1650.9 nm and Peltier-cooled Single Photon Avalanche Diode (SPAD) detectors in a Random Modulation Continuous Wave (RM-CW) Lidar system.

Gas Sensing LiDAR:    TDLiDAR

  • New type of LiDAR :        Tunable Diode LiDAR” ( TDLiDAR )
1. Tunable Diode Laser Absorption Spectroscopy ( TDLAS
2. Differential Absorption LiDAR ( DIAL
3. Time Correlated Single Photon Counting ( TCSPC
  • Uses eye safe infrared semiconductor lasers & single photon detection (“Geiger counter for light”) to count gas molecules in a plume from >200m distance
  • Scanning the laser around builds a 3D picture ( LiDAR point cloud ) of objects and gas showing the exact plume location & size
  • To date have produced cameras for imaging CH 4 & CO 2
