    摘要： A near-infrared spectrometer-based analyzer attaches continuously or semi-continuously to a human subject and is used to collect spectral measurements of a tissue sample. The spectral readings are used to estimate a biological parameter in the sampled tissue noninvasively, such as glucose concentration. The preferred apparatus is a near-infrared analyzer that includes a base module and a sample module connected together with a communication bundle. The base module contains the bulk of the analyzer, such as a spectrograph and a central processing unit with an algorithm used for converting the optical signal into a glucose concentration. The sample module is typically in a smaller module that interfaces to a tissue sample. The sample module is preferably handheld and provides minimal sampling distortion due to heat or pressure.
