Claim:
1. An apparatus for non-invasive glucose monitoring, comprising: at least one light source, emitting at least one ray of light; a first beam splitter with a focusing function, leading the light emitted from the light source into an eyeball and focusing on the eyeball through the first beam splitter; a polarizer; a set of light sensing elements, wherein the light sensing elements simultaneously measure at least two properties of the light reflected from the eyeball transmitted onto the set of light sensing elements, wherein one of the at least two properties measured comprises an absorption energy information of the reflected light transmitted by the first beam splitter, and another of the at least two properties measured comprises an optical angular information of the polarized light transmitted through the polarizer; a reference component, wherein the reference component receives the reflected light from the first beam splitter, wherein the reflected light is transmitted by the first beam splitter to the set of light sensing elements, wherein the light emitted from the light source is directed to the eyeball through the first beam splitter, reflected by the eyeball, and then transmitted to the set of light sensing elements by the first beam splitter to form a first optical path, and the light emitted from the light source, transmitted to the reference component by the first beam splitter is reflected by the reference component, and then transmitted to the set of light sensing elements by the first beam splitter to form a second optical path, and wherein the at least two properties of the light transmitted on the first optical path and the at least two properties of the light the second optical path are measured in sequence; and a processing unit, wherein the processing unit obtains a glucose information by receiving and analyzing the optical angular information and the absorption energy information by at least two polynomial equations, wherein the at least two polynomial equations comprises a first polynomial equation and a second polynomial equation, the first polynomial equation represents relationship between a biological molecule information and the optical angular difference, and the second polynomial equation represents relationship between the biological molecule information and the absorption energy difference, the biological molecule information comprises the glucose information.
