Fibre optic shape sensing colloquium: London 2019

Thomas Kissinger, in his role as a member of the Instrument science and technology group (ISAT) committee of the Institute of Physics,  organised a meeting entitled “Fibre optic shape and deformation sensing: an emerging technology” at the IoP in London 7th May 2019. The meeting featured presentations from researchers from the UK, Netherlands and Ireland with an interest in the development and practical application of fibre-optic based techniques for the measurement of shape. The talks covered applications in diverse areas, including  biomedical, aerospace, civil engineering, and flow measurement.

Nucleus STEM lecture: Optical Fibre Technology

In May, Steve James gave a lecture to Key-Stage 3 students at Northampton Academy as part of the Nucleus series of STEM (science, technology, engineering, mathematics) lectures.

Professor James talked about how optical fibres are produced, and how methods have changed to become more efficient. He demonstrated optical fibres and explained the history of optical fibres, which goes back a lot further than most people would expect. He also explained some of the uses of optical fibres, that go beyond the use in communications that we are most familiar with; including how optical fibres can be used as sensors for chemicals, gases, pressure and force. Some of the uses of optical fibres being studied and developed include testing rail components, the stress on aircraft wings and environmental sensors.

This led to some excellent questions from the students and expanded their interest in this field.

AIAA SciTech Forum: San Diego 2019

In January, Steve James travelled to the US to attend the American Institute of Aeronautics and Astronautics Science and Technology Forum and Exposition (AIAA SciTech) .  The paper he presented was part of a special session “BladeSense - A novel approach for measuring helicopter rotor blade deformation” at which members of the Bladesense project, including Steve, Simone Weber, and Mudassir Lone from Cranfield University, and Dominic Southgate from Helitune, gave a series of talks leading the audience through the project and progress to date.

Engineering Photonics member awarded Royal Academy of Engineering research fellowship

Engineering Photonics member Dr Thomas Kissinger has been awarded a prestigious fully-funded Research Fellowship by the Royal Academy of Engineering. Thomas is one of 17 engineers across the UK selected and the fellowship will provide £491,000 funding over five years, starting in November 2018.

In the project entitled “Doppler-Enhanced Lidar System Using Range-Resolved Interferometry”, Thomas will investigate a new type of interferometric 3D imaging system, originally based on work carried out during his own PhD at Engineering Photonics. This novel device can provide high-quality velocity and acceleration data in addition to 3D images and could potentially be beneficial across a wide range of applications, including manufacturing, robotics, autonomous vehicles and healthcare.

Rank Prize symposium: Grasmere 2018

In October, Jonathan Hallam and Ralph Tatam attended the Rank Prize symposium on fibre optic and photonic sensors for industrial and healthcare applications. The symposium was held at the Wordsworth Hotel in Grasmere, which is located in the beautiful Lake District National Park in Cumbria.

Jonathan presented his work on fibre-optic optical coherence tomography for high speed flow measurement applications, whilst Ralph discussed recent developments in engineering photonics for aerospace, manufacturing and healthcare.

The symposium was very much enjoyed with lots of three-course meals and a free bar that went on into the night.
