Description

[0002] In the field of machine vision, coaxial light is a special lighting technique in which the axis of the light source is coaxial with the imaging system, such as the camera lens. This layout allows the light to be directly incident on the observed object, almost perpendicular to the object surface. Because the angle of incidence of the light is very small, it can significantly reduce the generation of shadows and reflections, thereby providing more uniform and consistent lighting effects. This is particularly important for detecting objects with smooth or reflective surfaces in machine vision systems, as it can improve the accuracy and reproducibility of detection. Linear light sources have a wide range of applications, including camera module detection, automated vision detection, hardware detection, glass detection, printing detection, textile detection, automobile detection, and so on.
