Dither mechanism

WebSep 23, 1991 · The tuner for ring laser gyro dither mechanism shown herein is a disk 32 which is bolted to the top end 48 of a base mounted vane 24 of the gyro. All such base mounted vane top ends 48 are thus bolted together, thereby stiffening the spring constant of the azimuthal vibration 52 of the top ends 48, thus increasing the frequency of the dither … WebA dither mechanism comprises a hub (10) arranged to be fixed to a mounting, and a rim (11) coaxial with the hub and to which the ring laser may be attached. A number of radial spokes (12) interconnect the hub (10) and the rim (11), and each has its point of attachment to the rim (11) recessed into the rim in a radial direction. A pair of pegs (32) is associated …

WebOct 7, 2024 · This mechanism of oscillation, called dithering , is usually based on a complex mechanical system unable to completely eliminate the effect of the backscattering induced coupling. Moreover, sometimes the dithering vibrations cannot be applied to those ring laser gyroscopes mounted on platforms that are very sensitive to the vibrations. Webthe dithering mechanism needs to be ultra stable and maintained consistently. Hence control algorithms and hardware is implemented in RLGs for these three controls. Most of the algorithms implemented are linear algorithms and simple in nature. It is felt to use non linear algorithms based on the
