Blood composition analysis system and method combining absorption spectrum with reflection spectrum

The invention relates to a blood composition analysis system and method combining an absorption spectrum with a reflection spectrum. The system comprises a broadband light source, a light beam scanning device, a detected sample, an absorption spectrum information acquisition device, a reflection spectrum information acquisition device, a computer and a display system. The blood composition analysis system and method combine the advantages of a transmitted spectrum and the reflection spectrum and can effectively exclude the interferences caused by factors including measurement conditions, environmental factors, human physiological differences and the like; the problem that spectral information with a single wavelength is lost is solved and measurement errors caused by that spectrums of all blood compositions are overlapped can also be reduced; meanwhile, more abundant information is also provided for analyzing the blood compositions, and the accuracy and the creditability of an analytic algorithm result are im
