The patent or application file contains at least one drawing executed in color. Separate optic fibers carry each of the at least two beams through a region subject to vibration to a remote location where the information is recovered by an optical receiver based on the separate light beams. The apparatus may further include a camera positioned in an optical path of the optical housing, the camera being configured to receive an optical output of the optical component and transmit data representative of the output to the controller for use in controlling the press operation.
