A quantum resonance detector was a 24th century Federation sensor technology capable of detecting changes to the time stream.
History and specifics[]
It scanned the quantum resonance signature of the universe to monitor violations of the Temporal Prime Directive. It was a technological recreation of El-Aurian temporal sensitivity, invented for the Federation Department of Temporal Investigations thanks to research in the mid 24th century by Tosonal Undava with Wyannis, a retired El-Aurian agent.
Such detectors were used to determine the source of a change, so that DTI agents could investigate and prevent the incursion.
By 2368, detectors had begun production. They were mounted on shuttles, satellites and starships. Detectors were placed in orbit of key Federation planets, including Vulcan and Earth. The largest such detector was the classified Space-Time Anomaly Detection Array in orbit of Cassandra. (Last Unicorn RPG module: All Our Yesterdays: The Time Travel Sourcebook)
