Latest Patents

One of Johnson's latest patents is an optical fiber sensor system designed for sensing strain or temperature in aircraft. This system transmits information in communication systems and includes a sensor array with two light responsive Bragg grating sensors. Each sensor modifies light at wavelengths indicative of changes in strain or temperature, with the second sensor operating within a different bandwidth than the first. A tunable light source, such as an LED, illuminates the sensors, and a detecting circuit processes the modified light signals to determine strain and temperature.

Another significant patent is the dual frequency laser amplifier array and its operating method. This invention features a beam generator that produces first and second source laser beams. It utilizes a co-doped optical fiber with dopant ions that correspond to the gain bandwidths of the respective laser beams. This technology allows for the selective formation of diffraction-limited output laser beams based on the radiated power between the source beams.
