Abstract: Disclosed herein are an apparatus and method for controlling the capture of an image of a cut surface. The apparatus for controlling the capture of an image of the cut surface of material that is cut using a cutting device includes a signal generation unit for outputting a signal, a sensor unit for sensing the output signal using multiple sensors and generating a sensing signal, and an image capture control unit for controlling an image-capturing operation of an imaging device, which captures the image of the cut surface, using the sensing signal.

Abstract: Disclosed herein are a method for analyzing heavy metal removal efficiency using phase difference analysis and an apparatus using the method. The method for analyzing heavy metal removal efficiency using phase difference analysis includes applying a magnetic field to a magnetite onto which a heavy metal is adsorbed, based on a first solenoid coil and a second solenoid coil that have an identical winding direction, applying a high-frequency signal to the magnetite, based on a third solenoid coil having a winding direction that differs from that of the first solenoid coil and the second solenoid coil, detecting a high-frequency signal transformed by the magnetite, and calculating a phase difference between a previously detected default high-frequency signal and the transformed high-frequency signal, and analyzing an efficiency of heavy metal removal by the magnetite by measuring a concentration of the heavy metal based on the phase difference.
