Abstract
A detector for a test system having multiple indicators uses position sensitive light detection by multiple light detecting elements to produce a measured signal vector. The measured signal vector, which may include fewer components than there are indicators, has a magnitude and a direction that can identify how many and/or which set of the indicators are active. Analysis of the measured vector signal can use vector composition/decomposition techniques.
