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.

A photoreceptor protein-based spectrophotometer may include a field-effect transistor and a photoreceptor protein on the field-effect transistor (FET), the photoreceptor protein exhibiting change in electrical properties by absorbing light and being activated. Since the spectrophotometer can convert the light absorbed by the photoreceptor protein to an electrical signal using the FET, it can mimic human vision by using human photoreceptor proteins. The spectrophotometer can measure the color, intensity, etc. of light of broad wavelength ranges as in human vision. Thus, the spectrophotometer can be applied to the development of artificial vision, etc.

An apparatus for measuring ganglion cells may include: a light generation unit configured to irradiate a first light signal polarized in a first direction and a second light signal polarized in a second direction perpendicular to the first direction to a subject; a reflected light processing unit configured to generate an amplification signal corresponding to an image of the subject using a first reflection signal, which is the first light signal reflected from the subject, and a second reflection signal, which is the second light signal reflected from the subject; and an image processing unit configured to measure ganglion cells in the subject using the amplification signal. The apparatus may be used to count the number of normal ganglion cells in the retina by measuring a phase difference of two lights polarized in different directions. The apparatus may also be used to monitor the progress of glaucoma.
