Patent attributes
A method of assembling an opto-physiological (OP) sensor comprises: (i) modelling the opto-physiological properties of at least one body tissue type to be monitored; (ii) determining, through application of the model, an optimal optical design for an opto-physiological (OP) sensor operable to monitor the opto-physiological properties of the at least one body tissue type; and (iii) making the OP sensor to the determined optical design. The optimal optical design for the OP sensor comprises: (i) determining the optimum separation of each of a plurality of light sources from a photodetector, based on modelled optical path lengths for light travelling from each light source, through the body tissue type to be monitored, to the photodetector; and (ii) locating light sources of different wavelengths at different distances from the photodetector.
