Latest Patents

One of Itabashi's latest patents is an apparatus wherein diffracted light does not return to the source. This invention features a lattice interference-type displacement detection device that includes a scale with a penetration-type diffraction lattice. The optical system is designed to emit a light beam along a specific optical path, branching it into first and second divergence beams. These beams are incident at a diffraction point on the lattice, generating first and second mixing light beams that are converted into electrical signals. The design ensures that a second group of diffraction light beams is not reflected back to the light source, enhancing measurement accuracy.

Another significant patent is a displacement sensor that incorporates a heat insulating member. This innovation allows a semiconductor laser to be used as a light source while minimizing thermal effects. The sensor includes a spindle with a scale mounted in a housing, where a semiconductor laser projects a laser beam onto the scale. A heat insulation arrangement is strategically placed to prevent heat transmission from the laser to the scale, thereby improving measurement accuracy.
