Abstract: As
mechanical dither is widely applied to reduce frequency
"Lock-in" of RLG (ring laser gyroscope) that is based on the
principle proposed by Sagnac in 1913, it is necessary to know
the recent development in the field. The proper design of dither
mechanism that decides the effect of bias to some extent is
discussed. The proper dither signal and its control have a
direct influence on dither efficiency. Real, stable and accurate
error compensation can improve the performance of RLG further.
Some proposals, which are helpful to future research on the
field, are concluded.
Key words:
