Research Interests

My present research focuses on optical metrology, remote sensing, non-destructive testing and machine vision. We develop novel optical testing and other non-destructive testing techniques in different fields, such as freeform surface measurement, underwater detection, defect inspection, and defense applications.

Research Projects

Title: Aspherical and Freeform Surface Measurement with Compressed Sensing and Slope Measurement

Aspherical and freeform optics are used in a variety of applications, such as the digital and cellphone camera lens, projection systems, optical scanner, infrared imaging devices, and remote sensing imaging systems and so on. A fast and accurate non-contact freeform surface inspection system is developed using a combination of compressed sensing and optically random sampling schemes. The system reduces the resolution of sensor required while increasing the dynamic range of the system at comparable speeds and accuracy of a wavefront sensor.

Title: Underwater Target Detection Performance of pulse laser ranging system

Laser-based object detection has been recognized as the most reliable technique for applications such as night vision, 3D imaging, and especially underwater object detection. The key information is extracted from the reflected laser pulse after interacting with the target which directly affects the system performance. Due to the variety of the target types, it is necessary to investigate the surface characteristics and their effects on the performance of underwater pulse laser ranging system.

Title: Nanosecond pulsed laser ablation of graphite in liquids

Carbon-based material such as natural graphite was reported to exhibit exceptional thermal and electrical properties due to its unique structural construction. Currently, one of the promising technique of producing nanometre size particles is by using Pulsed laser ablation in liquid (PLAL) whereby a laser source is used to remove nanomaterial from a solid target in liquid to produce a colloidal solution. Hence, this study aims to synthesize graphite nanoparticles using PLAL in water on a graphite target.

Title: Automatic Detection and Repair Platform for Pavement Surface Cracks

Health monitoring and distress repairing are the most important activities in today’s transportation infrastructure maintenance. Regards of road system, cracking is the most common distress which can behave in various types such as fatigue crack, thermal crack and reflective crack. Crack allows water to intrude into pavement system and damage the road structure under traffic loading. Previous studies have showed that the pavement life can be significantly extended if the early-stage surface crack can be sealed timely. The aim of this study is to develop an automatic detection and repairing system for pavement cracks.
