Abstract: Provided is a cell-level retinal disease detection apparatus including a light imaging means configured to emit light to an eyeball and a light processing means which receives light reflected by the eyeball and processes and compensates light for an astigmatism aberration thereof which occurs at the eyeball to compensate. Here, the light processing means includes a wavefront sensor which senses the astigmatism aberration of the reflected light which occurs due to the eyeball and a light compensation mirror which compensates the light based on the sensed astigmatism aberration, and compensates for a difference in the astigmatism aberration to detect a disease of a retina of the eyeball.

Abstract: An optical logic gate includes: a DNA based nanostructure including DNA and metal nanoparticles coupled to the DNA, the DNA based nanostructure being configured to rotate a polarization plane of an incident light; a polarizer to which light passing through the DNA based nanostructure is incident, the polarizer being configured to extract a component in a direction of a predetermined reference axis from light whose polarization plane is rotated by the DNA based nanostructure; and a detection unit to which light passing through the polarizer is incident, the detection unit being configured to generate a logic signal based on a result obtained by comparing the intensity of the component in the reference axis direction extracted by the polarizer with a predetermined threshold value.
