Abstract
A ring laser gyroscope may be oscillated or dithered about its sensing axis to the known `lock-in` effect. The diether motion can comprise an alternating component plus a random component generated by a random noise generator, e.g. a noise diode. The use of a true random noise generator may not always be practicable. Herein, there is proposed the dithering of a ring laser gyroscope with a motion including a component having a specifically Gaussian probability density. Such a component can be formed using a so-called pseudo-random sequence generator based on a shift-register.
