Latest Patents

Daryl C Stjern was awarded a patent for an "Apparatus and method for correcting ring laser gyroscope phase angle." This invention focuses on measuring phase errors that occur when a dithered ring laser gyroscope enters its deadband. The method involves applying a correction to the output of the gyroscope to compensate for these phase errors. The technology utilizes counterpropagating beams in a ring laser gyroscope that are heterodyned to produce quadrature heterodyne signals, indicating the angular output of the laser. The invention effectively determines the phase angle error and produces a control signal to adjust the output of the gyroscope, correcting for errors introduced during the dither cycle.
