Title: Innovations of Inventor Feng Qian in Defect Detection Technology
Introduction
Feng Qian, an inventive mind located in Natick, MA, has made significant contributions to the field of optical defect detection. With two patents to his name, his work continues to push the boundaries of technological advancements in the industry.
Latest Patents
Feng Qian's latest patent focuses on a "System and method for detecting defects on a specular surface with a vision system." This innovative invention utilizes a knife-edge technique where the camera aperture or an external device creates a physical knife-edge structure in the optical path. This design efficiently blocks reflected rays from a smooth specular surface with specific slope values while allowing rays deflected at varying angles to reach the vision system camera sensor. The ingenious setup ensures that light reflecting from the flat areas of the surface is primarily blocked by the knife-edge, while light from the sloped areas of defects is predominantly admitted into the camera's entrance aperture. The illumination beam is strategically angled concerning the optical axis of the camera to optimize the incident angle for effective inspection. Notably, the system can accommodate both stationary surfaces and those in motion relative to the camera.
