摘要：
An apparatus, method and system for dermatologically noninvasive testing for blood sugar concentration using an interferometry optical design. The present apparatus, method and system are used to measure the optical properties of blood, without puncturing the skin or drawing blood samples. They incorporate the use of an electromagnetic light source and two optical polarizers. A dermatological sample, e.g., the earlobe, webbing between fingers, is illuminated with polarized electromagnetic light. When the linearly polarized light passes through this dermatological sample, the blood in the dermatological sample acts as an optical rotator due to the optical interaction with the blood sample. The presence of molecular chirality in the blood sample induces optical activity. After the skin is illuminated, a second polarizer finds the orientation of the polarization by maximizing the intensity on the photo detector. As a result, the blood sugar concentration may be determined.
