Surface Inspection Equipment

Wafer Structural Light Surface Shape Detection Equipment Applications Wafer flatness detection. Working Principle The point cloud distribution and curvature distribution of the measured surface are calculated according to the deformation of the light stripe, and the surface shape error distribution can be obtained by comparing the point cloud distribution with ideal model. Features Model SSD-W-X—X Measuring range 200×150mm2 Transverse resolution Conventional 0.25mm,

Lens Structural Light Surface Shape Detection Equipment Applications Lens surface shape detection. Working Principle Structured light measurement belongs to the active optical measurement.It usually projects some shape of structured light onto the object surface and obtain the 3D information of the object by detecting the offset distance of structured light.Finally,the 3D information of the object is determined according to the geometric relationships among the camera,

Car Paint Structural Light Surface Shape Detection Equipment Applications Car paint surface detection. Working Principle Structured light is the active structural information projected to the surface of the measured object by a projector, such as laser stripe, gray code, sine fringe, etc; however, structured light images are obtained by photographing the measured surface with a single or multiple cameras; finally, based on the principle of triangulation, the 3D reconstruction

Lamp Reflector Structural Light Surface Shape Detection Equipment Applications Lamp reflector shape detection. Working Principle Sine fringes generated from computer programming are projected onto the measured object by a projector. Using camera to photograph the tortuosity of fringes modulated by objects. The point cloud distribution and curvature distribution of the measured surface are calculated according to the deformation of the fringes, then the surface shape error
