从软组织来的反射光已经被利用来作为无创临床检测装置,如:光电容积描记和反射式脉搏计数等。入射光线通过皮肤进入下层组织一部分被反射回表面。文中描述了波长范围从420～940nm的反射光.它依赖于光学紊乱理论和从17个人体研究中得出的结论。结论表明,从510～590nm
Reflected light from soft tissue has been used as a non-invasive clinical testing device, such as photoplethysmography and reflective pulse counting. The incident light passes through the skin into the underlying tissue and is partially reflected back to the surface. The article describes the reflected light in the wavelength range from 420 to 940 nm and relies on the theory of optical disorders and conclusions drawn from 17 human studies. The conclusion shows that from 510 ~ 590nm
