QLM Publishes Technology White Paper
February 16, 2021

QLM’s first white paper, detailing the revolutionary quantum single photon detection technology behind the upcoming gas camera, is available from today.

The comprehensive paper provides an overview of the current need for continuous emissions monitoring, and reviews in brief the array of continuous solutions that are pushing to corner the market, including networked point sensors, open path spectrometers, and OGI and GCI cameras, summarising the advantages and disadvantages of each. It then introduces and discusses in detail the quantum single photon detection technique underpinning the SPLICE project, explaining how the Lidar and SPAD combine to visualise and quantify the shape and concentration of the detected gas, and summarising the key advantages this method holds over the alternatives.  Finally, it discusses some of the results generated in field trials of the prototype equipment over the course of the last year, and suggests where improvements will be made for the commercial product due for release this year.

The publication of the paper is a pivotal moment in the delivery of the SPLICE project’s vision for commercialisation of QLM’s technology, taking what has been achieved so far and presenting it as a comprehensive story. It represents a transition from describing what the quantum gas camera does to explaining how it does it, grounding the camera in the traceable scientific understanding and not only presenting the results, but offering a rigorous investigation of them and highlighting where improvements are going to come.

Further papers are planned, drawing comparisons between the results obtained by the prototype and those generated by the commercial release of the camera, and documenting the validation procedure used to assess the industrially relevant parameters of linearity, repeatability, intrinsic uncertainty and others against traceable standards. These will follow over the course of the SPLICE project, and reinforce the scientific introduction provided by the first publication.

PDFs of the paper are available on request.  Requests can be made via the contact forms either here or on QLM’s website – get in touch to obtain your copy today.
