对于新的光学体域网（BAN）技术，使用漫散射光进行通过人体的光学数据传输的基础研究。由于人体组织内部的强散射效应，限制了数据传输的频带宽度。在使用人体的实验中，证实了传输高达100 MHz的可能性。使用线性均衡过程，我们可以传输800 MHz方波信号。在人手中大约200 mm距离的数据传输是可能的。为了克服噪声、多径传输和数据传输瞬时中断等问题，空间分集（SD）技术被应用于稳定数据通信。通过使用真实的光脉冲响应的分析，证实了SD技术的有效性。通过这些分析，验证了利用人体漫散射光进行BAN的可行性。
For a new optical body area network (BAN) technique, a fundamental study was conducted of optical data transmission through a human body using diffusely scattered light. The frequency bandwidth for data transmission was restricted by the effect of strong scattering inside body tissues. In experiments using human bodies, the possibility of the transmission up to 100 MHz was confirmed. Using the linear equalization process, we can transmit an 800 MHz square wave signal. Data transmission of around 200 mm distance in a human hand was possible. To overcome problems of noise, multipath transmission, and the instantaneous interruption of data transmission, the space diversity (SD) technique was applied to stabilize data communications. The SD technique effectiveness was confirmed through analysis using real optical impulse responses. The feasibility of BAN using diffusely scattered light in the body was verified through these analyses.
