1. The system “growth” can be followed in real time by light absorption/emission detection. System examples: bacteria, cell cultures, plants, etc.
2. Biofilm. Biofilm growth can be followed on specific surface.
3. Biomass: Bioenergy
4. Light – Dark cycle measurements
5. Luminescence measurements
6. The photo detector matrix can be put on some specific environment like controlled environment chamber and the light specific functions can be followed there.
