The aim of this project is to demonstrate terahertz tomography, operating at millisecond image frame rates. The system will be based around a new high-power laser-diode driven nanosecond fibre-laser THz source, using difference-frequency generation, and pyroelectric detector arrays. The demonstrator will employ novel multi-channel THz tomography to map major species concentrations and temperature field distributions in high-pressure flames operating under sooting conditions. The proposed technology will also open the way to fast benchtop THz tomographs with applications in a wide area of science and engineering
