Abstract: The present disclosure proposes a new technical method for realizing a specific configuration for dynamically/optimally controlling an RF channel in consideration of both throughput of a cell and energy saving in an O-RAN system and realizing an interface operation between O-RAN equipment related thereto, enabling dynamic/optimal control of the RF channel of the cell according to the situation.

Abstract: A surface plasmon resonance imaging apparatus is provided. The surface plasmon resonance imaging apparatus includes a light irradiation unit configured to irradiate polarized light onto a metal coating film provided on one surface of a prism, a light modulator configured to spatially pattern-encode light reflected by the metal coating film and the prism, a light detector configured to detect a pattern-encoded light signal, obtained through pattern-encoding by the light modulator, as a spectral signal, a signal processor configured to spatially decode the spectral signal and analyze a decoded spectral signal to generate characteristic data of a sample provided on the metal coating film, and an output unit configured to output the characteristic data of the sample as a two-dimensional (2D) image.

Abstract: The disclosure relates to a non-dispersive infrared (NDIR) gas sensor which detects the concentration of gas with a simple structure and method by manufacturing an optical waveguide with a gas-permeable polymer material instead of a conventional cavity or chamber type. An optical signal travels through the optical waveguide of gas-permeable polymer by total internal reflection, and the gas naturally penetrates the optical waveguide without the use of separate inlet and outlet openings, so that the optical signal and gas particles come into contact with each other within the optical waveguide. Since the optical signal detected by a photodetector at the other end of the optical waveguide after traveling while contacting the gas particles has properties changed according to the concentration of the gas which they have contacted in the optical waveguide, it is possible to measure the concentration of a specific gas from the detected optical signal.

Abstract: A device and method for controlling a driving current with respect to an optical source of an optical disc drive are provided. The method includes changing a characteristic of a high frequency component based on a change in the peripheral temperature of on optical pickup device, modulating the driving current using the high frequency component, and applying the modulated driving current to the optical source.
