International Telemetering Conference Proceedings / October 26-29, 1992 / Town and Country Hotel and Convention Center, San Diego, California / A fiber optic event timing system was developed for the High Speed Test Track at
Holloman Air Force Base, Alamogordo, NM. The system uses fiber optic sensors to detect
the passage of rocket sleds by different stations along the track. The sensors are connected
by fiber optic cables to an electronics package that records the event time to a resolution of
100 nanoseconds. By use of a GPS receiver as the timebase, the event time is stored to an
absolute accuracy of 300 nanoseconds. Custom VMEbus boards were developed for the
event timing function, and these boards are controlled by a programmable high speed
sequencer, which allows for complicated control functions. Each board has 4 electro-optic
channels, and multiple boards can be used in a VMEbus card cage controlled by a single
board computer. The system has been tested in a series of missions at the Test Track.
