High resolution remote surface measurement system for inspection of tunnel walls

摘要：

　　We are developing a system for remotely inspecting concrete deterioration by using laser and sensor technology.We adopt three measurement principles: reflectance imaging, 3D measurement, and spectroscopy.We have realized high spatial resolution to detect cracks of more than 200 μm in width on a concrete surface.

关键词： laser tunnel crack concrete spectroscopy
