Micro focus industrial CT is an industrial computed tomography technology based on micro focus X-ray sources, mainly used for non-destructive testing and internal structural analysis of materials, parts, etc. Here is a detailed introduction about it: -
working principleMicro focus industrial CT uses micro focus X-ray tubes to emit X-rays. After the X-rays penetrate the object being detected, they are received by the detector, which converts the received X-ray signal into an electrical signal and then converts it into a digital signal through analog-to-digital conversion. Computers process these digital signals and use specific reconstruction algorithms, such as filtering and backprojection algorithms, to reconstruct three-dimensional tomographic images of objects, thereby achieving non-destructive detection of the internal structure of objects.

Technical Features
-
high resolutionThe spatial resolution can reach 1 μ m-10 μ m, which can detect very small defects such as tiny cracks, holes, etc.
-
high precisionThe size measurement accuracy can reach 1 μ m-10 μ m, which can accurately measure the size and position of the internal structure of objects.
-
non-destructiveWithout damaging the object being tested, a comprehensive internal inspection can be conducted to preserve the integrity of the object.
-
3D imagingIt can generate a three-dimensional model of an object, visually displaying the internal structural information of the object, facilitating comprehensive observation and analysis.
