【Non-Destructive Analysis】
SATScanning Acoustic Tomography (SAT), is a method for analyzing materials by measuring the reflecting speed and energy of an ultrasonic wave which is transmitted through the material of a certain thickness. When sound signals are transmitted, using pure water as the medium, and hit the interface of different materials, part of the signals reflects and part penetrates. The machine then collects the signals and forms them into images.

2D/3D X-rayThe X-ray imaging shining X-ray radiation is very powerful in penetrating objects. The level of penetration varies with the density of the substance contained in an object structure. The X-ray receives images based on the amount of penetrated energy. 3D X-Ray Microscope is a non-destructive method employed with an optical microscope to enhance the magnification, which uses 2D X-ray tomography to take sample images at all angles while turning the sample. The images of the tested object are then constructed by computer operation.

3D Laser OM3D Laser Optical Microscope (3D OM) captures the reflection of visible light from object surface with optical zoom-in and zoom-out and CCD for surface pattern observation and dimension analysis and measurement. Using laser source to measurement high accurate Z-axis profile.
