PhD topic – System for real-time monitoring and sensing railway conditions by laser light

Research summary

This project is looking to develop a Laser Speckle sensing system suitable for measuring stresses and strains in Australian rail tracks and cars. By using a beam of coherent light, illuminating a rough surface where reflection waves interfere with each other will result in a speckle being detected, helping engineers to measure deformation and identify the region with defects easily.

Expected completion date

February 2021

Key achievements

• Developed laser speckle optical system for non-contact, non-destructive and remote sensing of strain in railway applications.
• Demonstrated the performance of optical sensor for high-resolution strain measurements in both laboratory and field conditions.
• Published main research outcomes in four renowned international journals and 3 international conferences.
• Awarded Faculty of Engineering International Postgraduate Research Scholarship (FEIPRS).
