Patent number: 9833175Abstract: An apparatus for non-invasive blood glucose monitoring includes a light source for generating at least one ray of light, a beam splitter with a focusing function leads the light into an eyeball and focuses on the eyeball, a set of photo detectors for measuring optical angular information and absorption energy information of the light reflected from the eyeball and transmitted through the first beam splitter to the set of photo detectors, and a processing unit. The processing unit receives and processes the Optical angular information and the absorption energy information to obtain an Optical angular difference and an absorption energy difference between the light emitted from the light source and the light transmitted to the set of photo detectors, and analyzes the Optical angular difference and the absorption energy difference to obtain a glucose information, and since the glucose information has a corresponding relationship with a blood glucose information, the blood glucose information may be read.Type: GrantFiled: April 27, 2012Date of Patent: December 5, 2017Assignee: Taiwan Biophotonic CorporationInventors: Yu-Tang Li, Chang-Sheng Chu, Chih-Hsun Fan, Shuang-Chao Chung, Ming-Chia Li, Jyh-Chern Chen, Kuo-Tung Tiao

Publication number: 20170311853Abstract: A method for non-invasive glucose monitoring includes the following steps. At least one ray of light is emitted from at least one light source. The light emitted from the light source is leaded into an eyeball and focused on the eyeball through a first beam splitter. The reflected light reflected from the eyeball is transmitted through the first beam splitter to a set of photo detectors. Optical angular information and energy information of the reflected light transmitted to the set of photo detectors are measured. Optical angular difference and energy difference resulting from the light emitted from the light source and the reflected light transmitted to the set of photo detectors are obtained. Glucose information is obtained by analyzing the optical angular difference and the energy difference. Since glucose information has a corresponding relationship with blood glucose information, blood glucose information may be obtained.Type: ApplicationFiled: July 16, 2017Publication date: November 2, 2017Inventors: YU-TANG LI, CHANG-SHENG CHU, PEI-FANG TSOU, PEI-CHENG HO, KUAN-JUI HO
