Abstract: A double solenoid coil operates in accordance with input first and second signals to generate an electromagnetic field and to provide the generated electromagnetic field as a sample. Then, a signal corresponding to the generated electromagnetic field is received, amplified, and output by a double lock-in amplifier. Free radicals generated by the sample in accordance with the electromagnetic field are measured based on the signal output from the double lock-in amplifier.

Abstract: In an electronic nose apparatus and method based on spectrum analysis, 1) a gaseous sample is dissolved into a solvent in an impinger, and the sample dissolved into the solvent is introduced into an RF resonator, and 2) RF having various absorption spectra according to materials are generated in the RF resonator, and the type of gas is determined through spectrum analysis so that an electronic nose is implemented. In this way, it is possible to overcome the resolution of gas chromatography (GC) and a sensor array and a limited number of multi-channel sensors (the number of channels).

Abstract: Provided are an image system and an image reconstruction method using the same. The image system includes an image scan device, a spectrum signal generation device, and an image recovery device. The image scan device generates a magnetic particle detection signal on the basis of an induced magnetic field induced from a magnetic particle. The spectrum signal generation device transforms the magnetic particle detection signal to a detection spectrum signal on the basis of a two-dimensional Fourier transform kernel. The image recovery device generates an image signal on the basis of the detection spectrum signal and a system matrix. According to the inventive concept, a data amount for image reconstruction may be ensured.
