Many applications in biology, medicine, and material science have a demand for a time and spatially resolved detection of luminescence, particularly in the near infrared spectral region. For example, observation of singlet oxygen phosphorescence is important in understanding cell-cell interactions as well as for research involving photo-dynamic therapy. Furthermore, investigating the temporal behavior of semiconductor luminescence has become an important quality indicator for the quality of wafer material, especially many kinds of solar cell research and production.
