Abstract:
A portable imaging device comprises: a fixing part for fixing portable photographing equipment; and an optical assembly generating a first light polarized in a first direction and a second light polarized in a second direction vertical to the first direction, irradiating the first and second lights to a target object, and generating a coherent light by combining the first and second lights reflected from the target object. The fixing part comprises an optical window aligned with the optical assembly so that the coherent light can be entered into the photographing equipment. The device can observe minutely transparent or untransparent matters by observing the phase difference between the two lights polarized in different directions. The device can be portable, so it can easily observe at desired locations.
Abstract:
A photoluminescence wavelength tunable material comprises a composite including a graphene oxide layer and metal nanoparticles attached on the graphene oxide layer. The photoluminescence wavelength of the graphene oxide (color of emitted light) can be tuned while a structure and physical properties of the graphene oxide is maintained by boding the metal nanoparticles to the graphene oxide. The photoluminescence wavelength tunable material can be applied to an energy harvesting element such as a solar cell with low loss and high efficiency.
Abstract:
A photoreceptor protein-based spectrophotometer may include: a field effect transistor (FET); and photoreceptor protein positioned on the FET, and causing a change in the electrical characteristic by being activated by the absorption of light. The spectrophotometer can copy the human visual organ directly using the human photoreceptor protein by converting light absorbed by the photoreceptor protein into an electric signal using the FET. The spectrophotometer can measure color, intensity, etc. according to the wavelength of light, such as the human visual organ, in combination, and can be applied to the development of an artificial visual organ or the like.
