The image of Computed Tomography (CT) is of good quality and highresolution. It can be processed and analyzed digitally Therefore, CT has become anew nondestructive detection technique, which is applied widely in aviation,shipping, automobile, public security and other areas.
Impact-echo method is a new non-destructive testing technology,the thickness and quality of structure concrete is judged by incepting and analyzing echo signal.
A platform for detecting human skin tissue absorption spectrum composed of optical fiber spectrometer and virtual instrument was described. It use optoelectronic nondestructive testing techniques and the method which measuring the reflection of skin.
A platform for detecting human skin tissue absorption spectrum composed of optical fiber spectrometer and virtual instrument is described. Optronic nondestructive testing techniques and the method which measuring the reflection of skin are used. The platform is available for using in the fundamental research of photon-tissue interaction as well as clinical testing in laser cosmetology.
This article describes the application status of the NDT technology in the manufacture and maintenance of locomotives and rolling stock on the SNCF railways.
Magnetic nondestructive testing techniques were used to inspect and estimate the level and distribution of residual circular stresses in tubes used in construction of main gas pipelines in the initial state before operation.
Two nondestructive testing techniques show promise as methods for measuring the stresses or cold work imparted on the surface of the work piece by peening.
In recent years, studies on the reflection properties of concrete with varying material content have been performed using microwave nondestructive testing techniques.
