ABSTRACT:
The angular speed measuring device has two acceleration sensors mounted on a circular plate rotating about a first rotation axis and each sensor generates a signal depending on a Coriolis force produced when it rotates about two additional rotation axes. The rotation axes are orthogonal and the acceleration sensors are at least partially made of silicon and displaced by 180.degree. on the planar plate. An initial signal processing device is mounted directly on a circular planar plate on which the acceleration sensors are mounted. A light emitting diode is used to transmit the signals from the initial signal processing circuit to a signal processing circuit off the planar plate via a photodiode receiving device.
