APPARATUS FOR MEASURING HEALTH INDEXES IN RETINAL VESSELS USING AN OPTICAL SENSOR AND METHOD FOR PROCESSING LIGHT REFLECTED FROM VESSELS FOR CALCULATION OF HEALTH INDEXES

摘要

A portable apparatus for measuring a health index includes a light source which emits infrared rays to a retinal vessel of an object, a photodiode which receives light reflected on the retinal vessel, and a processor which calculates a value related to the health index of the retinal vessel by measuring the intensity of the light inputted to the photodiode. Thereby, the health index is conveniently, safely, and precisely measured in the retinal vessel by using the transparency of an eye to the retina with regard to the light.
