Abstract
A fiber optic probe incorporating a luminescent composition is used to monitor conditions within a living subject. Response light from the fiber optic is detected and a frequency domain representation of the response light is derived. Characteristics of the frequency domain representation are used to derive values for luminescence lifetimes or similar decay parameters and these values in turn are translated into values of the conditions to be sensed.
