ABSTRACT:
A phase shift measurement system comprises an excitation system, a luminescent material, and a detection system. The excitation system transfers an excitation light wave. The luminescent material transfers a luminescent light wave in response to the excitation light wave. The detection system detects the luminescent light wave and generates a corresponding luminescent signal. The detection system processes the corresponding luminescent signal with DFT logic to determine a phase shift between the excitation light wave and the luminescent light wave.
