Yi Seed Yang He Xue Red element degree of saturation Liang Measuring methods, first offer Dai Measuring blood and Ginseng examine anti-She Mirror. Now Right Dai Measuring blood and Ginseng examine anti-She Mirror irradiation lights Line, and Ginseng examines anti-She Mirror and provides the first the reflected beams, and the backscattering of the different depth of Qie Dai Measuring blood provides the second the reflected beams. Obtaining the first anti-interference light News No. Hou for penetrating light beam With the second the reflected beams interference effect institute Productivity lifes, root According interference lights News No. Come obtain the first smooth wave Long Fan Wai Right whats and wait for that the first of Measuring blood declines the normal Number of Minus, and obtain the 2nd smooth wave Long Fan Wai Right whats and wait for that the 2nd of Measuring blood declines the normal Number of Minus. Most Hou obtains the first normal Number Right the 2nd of Minus that decline and declines the Minus ratios that decline of the normal Number of Minus, and the And roots According Minus ratios that decline obtain and close blood Red element degree of saturation to the oxygen of Measuring blood.一種氧合血紅素飽和度量測方法,首先提供待測血液及參考反射鏡。接著對待測血液及參考反射鏡照射光線,參考反射鏡提供第一反射光束,且待測血液之不同深度之逆向散射提供第二反射光束。在取得第一反射光束與第二反射光束干涉作用所產生的干涉光訊號後,根據干涉光訊號來取得第一光波長範圍對於待測血液之第一衰減常數,以及取得第二光波長範圍對於待測血液之第二衰減常數。最後,取得第一衰減常數對第二衰減常數之衰減比例,並根據衰減比例取得待測血液之氧合血紅素飽和度。
