Latest Patents

One of Iwasaki's latest patents is a sensor for measuring magnetic fields by utilizing the principle of optically detected magnetic resonance (ODMR). This sensor includes two magnetic sensors that detect the magnetic field around an object and output magnetic field and temperature signals. The design features an optical system that emits excitation light to the sensors, and a processor that calculates the difference between the magnetic fields detected. Each magnetic sensor comprises an element with color centers, an antenna for radiating a microwave magnetic field, and an optical sensor that detects fluorescence intensity. The controller then calculates the magnetic field and temperature around the measurement object.

Another notable patent is a physical state measurement device. This apparatus consists of a main solid material that generates fluorescence when excited by light. A microwave application part controls the electron state of this solid material, while a detection part measures the physical state of an object through the fluorescence emitted. The feedback part detects amplitude differences in the electron spin resonance spectrum and adjusts the microwave application accordingly.
