Correlations with Thermal Light (IMAGE) Joint Quantum Institute Caption Coherent light passes through a pair of slits (top center). The two resulting concentric trains of waves will interfere, resulting in a fixed pattern when measured by a detector (top right). Non-coherent thermal light passes through slits and meets with a beam splitter (green plane), which reflects half the waves toward one detector and the other half toward a second detector (lower left). Each of the detectors records a temporary interference pattern (lower right).
