Transpectral sensor array

The transpectral sensor array was a type of sensor array that Professor $𝜇$ was developing in the early 2370s in the mirror universe for the Alliance. The purpose of the array was to detect the Terran Rebellion bases in the $𝜇$ and enable the $𝜇$s and the $𝜇$s to launch an assault.

In 2371, $𝜇$ kidnapped Benjamin Sisko from Deep Space 9 and brought him to the mirror universe. O'Brien hoped Sisko would be able to convince Jennifer to stop work on the array and join the Terrans. Sisko was successful and Jennifer stopped work on the array and left $𝜇$. 

The Alliance forces on $𝜇$ later began research into recreating Professor's Sisko's original research on the transpectral sensor array.
