Latest Patents
Kamada's latest patents include an "Optical Pumping Magnetometer" and a "Magnetic Field Measuring Apparatus and Method for Manufacturing Same." The Optical Pumping Magnetometer enables stable magnetic field measurement without the collapse of polarization or fluctuations in the intensity of the laser beam incident on a glass cell of an optical pumping magnetic sensor. This invention utilizes excitation light generated from a light source with optimized light intensity and polarized wave, introduced via a polarized wave holding optical fiber to a magnetic sensor within a magnetic shield. The measurement is performed through optical pumping, leveraging the magneto-optical properties of spin-polarized alkali metal.
The second patent, the Magnetic Field Measuring Apparatus, is designed to facilitate pressure control in a gas cell. It allows for the inspection of the internal pressure of the gas cell without requiring any special processes. The apparatus features a structure that includes a first hollow portion and a second hollow portion, separated by a first isolation wall. Additionally, the method for manufacturing this apparatus involves breaking the first isolation wall after generating alkali metal.
