Claim Text:
1. An optical measuring device comprising: a light emitting component comprising a light source configured to emit each of two different wavelengths of light, wherein the light emitting component is disposed within the optical measuring device to emit light onto a human body when the light emitting component is placed adjacent to the human body; one or more processors; a program memory coupled to the one or more processors and storing executable instructions that, when executed by the one or more processors, cause the optical measuring device to: a light reception component comprising a plurality of photodetectors positioned at a plurality of distances from the light source, the light reception component configured to: wherein the program memory further stores executable instructions that, when executed by the one or more processors, cause the optical measuring device to: implement an absorption computation unit that for each of the two wavelengths, computes a light absorbance in the uterine muscle layer based on the computed first spatial slope, the computed second spatial slope, and a thickness of the skin and fat layer, and that, based on the light absorbance in the uterine muscle layer for each of the two wavelengths, computes a concentration of at least one of oxygenated hemoglobin or deoxygenated hemoglobin of the uterine muscle; and an output component configured to receive and present one or more of the computed concentration of the at least one of the oxygenated hemoglobin or deoxygenated hemoglobin of the uterine muscle.
