Abstract:
휴대용 건강 지표 측정 장치는 대상체의 망막 안쪽에 있는 혈관으로 적외선을 조사하는 광원; 상기 망막 안쪽에 있는 혈관에서 반사된 빛을 받아들이는 광 다이오드; 및 상기 광 다이오드로 입사된 빛의 세기를 측정하여 상기 망막 안쪽에 있는 혈관의 건강 지표와 관련된 값을 연산하는 프로세서를 포함할 수 있다. 이에 따라, 눈이 빛에 대하여 망막까지 투명하다는 점을 이용하여 편리하고 안전하게 망막 안쪽의 혈관에 있는 건강 지표를 정밀하게 측정할 수 있다.

Abstract:
The present invention relates to an optical logic circuit and a method for generating logic signals using a DNA-based nanostructure. The optical logic circuit includes: a DNA-based nanostructure including a DNA and a metal nanoparticle coupled with the DNA, and to rotate a polarized surface of incident light; a polarizer which receives light transmitted through the DNA-based nanostructure, and extracts a component of a predetermined reference axis direction from light in which the polarized surface is rotated by the DNA-based nanostructure; and a detector which receives the light transmitted through the polarizer and generates a logic signal based on a comparison result of a size of a component of the reference axis direction extracted from the polarizer with a predetermined threshold value. The optical logic circuit is implemented based on a rotating characteristic of a polarized surface of the DNA-based nanostructure and may perform optical logic calculation using light having weak intensity. An advantage of optical calculation having rapid information process may be implemented so that a low power information processing technology advantageous for an energy user efficiency side is expected.Further, circuit elements may be designed to have a very small size of 10-9 m to represent excellent miniaturization and integration.
