Embodiments of the present invention relate to wear measurement. A system according to one embodiment includes a transport mechanism for running a tape across a wear structure and a measuring device for optically measuring an extent of wear of the wear structure by directly optically detecting a back of the tape. A method according to one embodiment includes positioning a tape across a wear structure and optically determining a first position of a back of the tape by directly optically detecting the back of the tape. The tape is rim across the wear structure for a period of time, and a second position of the back of the tape is optically determined by directly optically detecting the back of the tape after the period of time. A difference between the first and second positions is determined.
