A system for measuring a chain parameter of a moving chain is provided, wherein the chain has a repetitive structure such as a chain link or teeth in a cogged belt. The system comprises at least one optical sensor positioned and configured to receive light from the moving chain, and a processor functionally associated with the optical sensor. The processor is configured to obtain from a signal stream received from the optical sensor a chain parameter characterizing the chain while the chain moves. An Image Monitoring Unit (IMU), comprising the optical sensor, may be assembled proximal the chain of a bicycles or of a spin bike, and a Human Computer Interface (HCI) unit comprising a display and functionally associated with the IMU, allows a user to view measurement results of a chain parameter and to operate the system. A method of measuring a chain parameter of a moving chain is also provided. |
