Latest Patents

Dong Chu holds a patent for a groundbreaking invention titled "Multiplexable optical fiber displacement, strain acceleration." This patent describes a method for measuring displacement using two overlaid parallel optic gratings as the sensing elements of a sensor head. The system employs optic fibers as the transmission media between the sensor head and a central signal processing unit. The light intensity signals of Moire fringes generated by the overlaid optic gratings are transmitted through optic fibers to the central signal processing unit. By digitally counting the number of Moire fringes, the changes in both direction and magnitude of the displacement are measured. Additionally, multiple sensor heads can be multiplexed through a common optic fiber link to create a multipoint sensor system. This sensor system can also be modified to measure other physical quantities such as strain, acceleration, and pressure.
