摘要
En 中文
In this study, a new image-based sensor with high accuracy was developed. This wireless sensor is composed by optical sensor, micro-processor, wireless modules and rechargeable battery. Highly sensitive digital sampling moire (DSM) method is used to calculate displacements Its high accuracy was demonstrated by a numerical simulation, and a laboratory test was conducted to verify its applicability in crack monitoring.
