Contact Dr Tom Charrett

Areas of expertise

  • Instrumentation, Sensors and Measurement Science
  • Sensor Technologies


Tom is a Lecturer in Optical Sensors in the Centre for Engineering Photonics at Cranfield University and has over 15 years experience in instrumentation research, including image and signal processing, interferometry and laser speckle techniques.

He is a trained physicist  (MPhys Physics with Space Science and Technology, University of Leicester, 2002) and joined the Centre for Engineering Photonics to study for his PhD into the development of imaging Laser Doppler velocimetry instrumentation (2003-2006). Since 2006 he has been engaged in a variety of research projects with the Centre for Engineering Photonics, first as a Research Fellow (2006-2015) before being promoted to Lecturer in 2015.

Research opportunity

PhD in Fibre Optic Shape Sensing for robotics  - A fully funded (UK nationals only) PhD studentship is currently available to investigate the application of fibre optic shape sensing in robotics.

Current activities

Dr Charrett's current research interests include:

The development and application of novel laser speckle instrumentation;
- Speckle velocimetry for autonomous vehicle navigation and manufacturing robotics tool speed measurement. 
- The development of laser speckle techniques for the non-contact positioning for applications in manufacturing robotics.
