Luminescence decay-time-based optical sensors
The situation in the recording branch is about the same for both methods of decay-time measurement: as long as decay times longer than some tens of nano- seconds are involved, phase

These optical transducers make use of an ordinary DRAM chip whose ceramic package has had the lid removed so as to allow light to fall on to the memory cells, as shown in Figure 3.19:
