Abstract:	摘要： In this paper, a new reflective pulse oximeter is proposed and demonstrated with implanting a Fresnel lens, which enhances the reflected signal. An optical simulation model incorporated with human skin characteristics is presented to evaluate the capability of the Fresnel lens. In addition, the distance between the light emitting diode and the photodiode is optimized. Compared with the other reflective oximeters, the reflected signal light detected by the photodiode is enhanced to more than 140%. •A new reflective pulse oximeter is proposed and demonstrated with implanting a Fresnel lens, which enhances the reflected signal.•An optical simulation model incorporated with human skin characteristics is presented to evaluate the capability of the Fresnel lens.•The useful design of this reflective pulse oximeter would enable the application of low-cost device of continuously monitoring of daily activity. 出版者： Elsevier B.V 出版日期： 2016-09-15 出處： Optics communications, 2016-09, Vol.375, p.9-14 資源來源： Elsevier ScienceDirect Journals Complete 版權： 2016 Elsevier B.V. 識別號： ISSN: 0030-4018 識別號： EISSN: 1873-0310 識別號： DOI: 10.1016/j.optcom.2016.04.058
