Optical inspection is an important part of the quality process in manufacturing. It can range from quick, subjective inspection by a person to automated quantitative inspection by a machine. It can be performed off-line, where the part is removed from the manufacturing process and brought to the inspection station; on-line, where the part is inspected without removing it from the manufacturing process; or near-line, where the part is inspected near the manufacturing process so it can be returned to the manufacturing process as quickly as possible.
