What kind of sensor can be used to detect whether the shape of aero-engine turbofan meets the machining accuracy requirements?

It is suggested to consult Chifeng precision steam turbine blade inspection system, which uses non-contact optical scanning probe to obtain the complex geometric structure and size information of blades completely, so as to obtain GD&: T, internal morphological characteristics, roughness, cracks, deformation and defects.

Based on the principle of low coherence interference, the system guides the light beam to the surface by rotating the non-contact probe and collects the reflected signal, thus obtaining the information of the inner diameter surface. The system obtains micron-scale high-precision three-dimensional terrain features point by point at a speed of 30,000 points per second.
