Use new optical element with coaxial line scan light can be used for detection of bump on smooth surface. The light source is equipped with a grating element. When a bump is detected, the fringe image will be deformed, and the deformation position is the position of the bump.
By changing the focal length of the lens, different sizes of field of view (FOV) can be obtained.
Machine vision obtains the required information or is a device used to control machine movement by analyzing images. It collects image information through image sensors such as industrial cameras, and controls the subsequent process actions of automated equipment by analyzing and processing the converted image information.
Industrial lenses are very important imaging components in machine vision systems. If the system is to fully play its role, industrial lenses must meet the requirements. With the widespread application of machine vision systems in the field of precision measurement, ordinary industrial lenses are difficult to meet the requirements, and telecentric
