Areas of expertise

  • Instrumentation, Sensors and Measurement Science
  • Sensor Technologies


Dr Jane Hodgkinson joined Cranfield University from the natural gas industry, where she was responsible for developing and testing new sensing technologies, particularly optical sensors for gas leaks. Jane obtained her PhD in 1998 from the Optoelectronics Research Centre at the University of Southampton, working in a collaboration with United Utilities on photoacoustic and photothermal detection of trace chemicals in water. She gained her first degree in Natural Sciences (Physics, 1st class hons) from Cambridge University in 1989.

Developing advanced tools for optical gas detection with improved levels of robustness and lower complexity, aiming to move this important technique from the laboratory and into the field.

Current activities

Use of diffusely scattering surfaces and integrating spheres within optical gas absorption cells, to ease alignment problems and reduce optical interference fringes. This includes investigating the effects of associated interference phenomena, including laser speckle behaviour in TDLS.

Development of next generation non-dispersive infrared gas sensors, using newly developed light sources and configurations for folded light paths.

Novel, low volume gas cells for healthcare applications.

Optical fibre gas sensors, exploiting synergies within the Centre and using in-house fabrication facilities.

Technology transfer to the gas detection industry, including collaborative projects with Geotechnical Instruments Ltd, Alphasense Ltd and Cascade Technologies Ltd.

Chair of the Gas Analysis and Sensing Group (GASG), a UK technology club bringing together users, sensor and instrument manufacturers, consultants and academics. See
