Abstract: A multi-channel measurement device for measuring properties of human tissue, may comprise a microcontroller and first and second source/sensor complexes. The first source/sensor complex may include a first housing having a first measurement portion, a first light sensor coupled to the microcontroller and exposed to the first measurement portion, and a first plurality of light sources coupled to the microcontroller and exposed to the first measurement portion. The second source/sensor complex may include a second housing having a second measurement portion, a second light sensor coupled to the microcontroller and exposed to the second measurement portion, and a second plurality of light sources coupled to the microcontroller and exposed to the second measurement portion. The first and second source/sensor complexes are coupled to each other such that the first measurement portion is opposite the second measurement portion and human tissue may be placed between the the first and second measurement portions. The microprocessor is configured with instructions stored in non-volatile memory to individually activate each of the light sources of the first and second pluralities of light sources and to record light intensity detected by the first and second light sources while an individual light source is activated. Each combination of an individually activated light source and one of the first and second light sensors provides a distinct measurement channel for measuring the absorption spectra of human blood and tissue.

Abstract: A multiple wavelength optical system includes plural solid state light sources, an optical diffuser, a lens assembly, and at least one photodetector. The solid state light sources have different wavelength ranges respectively. The optical diffuser has an incident surface and an exit surface opposite to the incident surface. The solid state light sources are disposed opposite the incident surface, and the lens assembly is disposed opposite the exit surface. Each of the solid state light sources faces the incident surface in the same direction. The lights of the solid state light sources enter the optical diffuser and exit from the exit surface, and then are focused by the lens assembly. Finally, the focused lights are projected on a surface of an object. At least one photodetector receives the reflected lights and the penetrating lights from the surface of the object.

Abstract: A method, apparatus and system estimating channel power, and monitoring a frequency spectrum characteristic. A method for estimating channel power includes extracting frequency spectrum information from a received signal, so as to obtain a frequency spectrum of the received signal, estimating power of a central channel in the frequency spectra according to a power value of a flat area of the central channel, and estimating power of a neighboring channel in the frequency spectra according to a power value of a flat area of the neighboring channel. With the embodiments of the present disclosure, the power of the central channel and the power of the neighboring channel may be estimated by using only frequency spectrum information obtained by a single optical receiver, so as to quantitatively evaluate influence of a power imbalance effect, thereby ensuring precision of the power estimation, and reducing effects of nonideal factors on the estimated values.
