Description of the identified functional, technical and design uncertainties of the proposed sensor concept approach and possible solution mechanisms.

		Solution Mechanisms
Functional	Technical/Design
Significant RGB measurement	Position and characteristics of the optical elements (light source, RGB detector, optical back element, etc.) to maximize RGB measurement dynamic range (Optical Subsystem Design).	▪Theoretical approach ▪Simulation ▪Prototypes development and tests
	Sample cavity design to guarantee a correct sample acquisition: cavity filling, air evacuation and fluid sample renewal (Fluidical-Mechanical Subsystem Design).	▪Simulation ▪Prototypes development and tests
Stable RGB measurement	Dependency between the light source variability versus temperature and the RGB measurement variability, and required stability control mechanisms (Optical Subsystem Design).	▪Theoretical approach ▪Simulation ▪Prototypes development and tests
