摘　　要：Noninvasive gluoose monitoring development is critical for diabetic patient continuous moni-toring.However,almost all the available devices are invasive and painful.Noninvasive methods such as using spectroscopy have shown some good results.Unfortunately,the drawback was that the tungsten halogen lamps 1usage that is impractical if applied on human skin.This paper compared the light emitting diode(LED)to traditional tungsten halogen lamps as light source for glucose detection where the type of light source plays an important role in achieving a good spectrum quality.Glucose concentration measurement has been developed as part of noninvasive technique using optical spectroscopy.Small change and overlapping in tungsten halogen results need to replace it with a more convenient light source such as LED.Based on the result obtained,the performance of LED for absorbance spectrum gives a signifcantly different and is directly proportional to the glucose concentration.The result shows a linear trend and scucssully detects lowest at 60 to 160 mg/dL glucose concentration.
