Detection and Characterisation of Surface Cracking using Scanning Laser Techniques
The use of lasers for generating and detecting ultrasound is becoming more established in non-destructive testing. However, there is still scope in developing the techniques to fully realise the benefits of non-contact measurements. One application is the detection of surface defects in metals; for example, rolling contact fatigue in rails, and surface cracking on billets or plates. We present ...
متن کاملSurface Clustering from Airborne Laser Scanning Data
This paper presents an algorithm for the extraction of surface clusters from airborne laser data. Surface structure analysis is fundamental to almost any application involving LIDAR data, yet most algorithms focus only on identifying planar segments. The proposed algorithm is more general insofar as it aims at extracting surface segments that exhibit an homogeneous behavior, without restriction...
متن کاملNear-field Scanning Optical Microscopy of Photonic Crystal Laser
Near-field scanning optical microscopy (NSOM) is a powerful alternative method to observe the optical intensity distributions in fabricated nanophotonic structures. Several groups have obtained NSOM images of photonic crystal (PC) [1-2]. Quite recently, we have reported the optical mode images obtained by NSOM on compact PC cavities based on fractional edge dislocations [3]. Here we report high...
متن کاملScanning and Image Reconstruction Techniques in Confocal Laser Scanning Microscopy
Taking advantage of the laser scanning methodology, confocal microscopy has been widely applied in cutting-edge biological research for its three-dimensional, high-resolution imaging capability (Pawley 1995). The principles of confocal were put forward by Marvin Minsky in 1955 (Minsky 1988), yet the experimental demonstration was not accomplished until 20 years later by Cremer brother (Cremer, ...
متن کاملA comparison between photogrammetry and laser scanning
A comparison between data acquisition and processing from passive optical sensors and airborne laser scanning is presented. A short overview and the major differences between the two technologies are outlined. Advantages and disadvantages with respect to various aspects are discussed, like sensors, platforms, flight planning, data acquisition conditions, imaging, object reflectance, automation,...
