Force Detector
a device rumored to have been developed by Emperor Palpatine, the Force Detector used two unique sheet-crystal paddles and a control pack to determine whether or not a person was Force-sensitive. The designs for the Force Detector were based on the work of Jenna Zan Arbor, who never fully realized a working prototype. Thaissen crystals, found only on the planet Circarpous V, were used in the paddles. If the person had some sensitivity to the Force, a bluish aura was displayed around them when the detector was activated. An individual with a strong connection to the Dark Side of the Force registered a reddish aura. The strength of the aura had come correlation to the amount of Force sensitivity the person had. Anyone without Force sensitivity did not register the blue aura. This sensor system was based on the recognition systems of Sith Dark Eye probe droids. It was believed that some 10,000 of these devices were created for Emperor Palpatine, who ensured that each one of them was approved by Lord Cronal.
