unitized car bodies. The example shown in fig. 5 is that of 
measurement of door line variation of a unitized car body, 
as the body is subjected to various forces. Other ap- 
plications are found in collision testing. 
Reusable LED packages are glued onto the subsystem in 
the selected locations. MNS simultaneously measures the 
displacement of each individual LED at a maximum 
measurement frequency of 2 Hz. The measurements are 
initiated by the operator through the MNS keyboard, or 
externally triggered by a TTL signal to synchronize to the 
applied force.
