Prior information is easily obtained in many applications of compressed sensing. This paper considers the sparse signal recovery using certain types of prior information. Our major contribution is proposing two novel reconstruction algorithms with prior information named as logit weight simultaneous orthogonal matching pursuit (LW-SOMP) and logit weight simultaneous orthogonal matching pursuit with...
Carbon fibre reinforced plastic (CFRP) materials are widely used in aircraft and wind turbine blades due to the low weight and high strength. Surface cracks, impact damage and delaminations are the most common defects for CFRP composites. In this paper, a pulsed eddy current (PEC) stimulated thermography is developed to detect and characterise these three types of defects from the heating patterns...
Recent developments in non-destructive evaluation (NDE) have concentrated in two directions: 1) sensors and arrays for local material/defect detection at both macro and/or micro levels; 2) large-scale component imaging and monitoring such as thermography. In this paper, microwave heating is proposed for defect detection of glass fibre reinforced plastic (GFRP) composite material in far field. Such...
This paper reviews the state-of-the art of modelling, simulation and visualisation and reviews the recent development of modelling, simulation and visualisation software for Nondestructive Evaluation (NDE). Simulation and visualisation can assist in the design and development of electromagnetic sensing and imaging techniques and systems for nondestructive testing, feature extraction and inverse problems...
