    • In one type of an angular velocity sensor, a constant vibration is applied in an X direction to one end of a vibrator which is fixed at another end and the vibrator vibrates in a Y direction perpendicular to the X direction by an action of Coriolis force caused by the angular velocity of the vibrator about the Z axis with an amplitude proportional to an angular velocity about a Z axis. An angular velocity sensor of this invention utilizes a photoelectric encoder for measurement of the vibration amplitude of the vibrator in the Y direction. The encoder includes a main scale mounted on the free end of the vibrator; an index scale mounted on a housing of the sensor to face the main scale; and a photoelectric element for sensing light reflected from the main scale and passing through the index scale. The angular velocity sensor utilizing the photoelectric encoder is less subject to influence of variation in the temperature in comparison with the conventional sensor utilizing piezoelectric elements and a higher precision can be attained.

    • A first grating is formed on a main scale, and a second and third gratings on an index scale. The first grating generally assumes a cruciform shape, and consists of a grating having grating lines arranged in the X-direction and another grating having grating lines arranged in the Y-direction. The second grating is formed in a square central area of the index scale, and consists of two gratings having grating lines arranged in the X-direction and divided at the center and another two gratings having grating lines arranged in the Y-direction and divided at the center. The third grating consists of four gratings having grating lines arranged in the X-direction with different phases and another four gratings having grating lines arranged in the Y-direction with different phases. A light-emitting element and eight photodetectors that are arranged corresponding to the respective gratings of the third grating are fixed to a movable member on which the index scale is attached. Light emitted from the light-emitting element passes though the second grating, reflected by the first grating, passes through the third grating, and finally detected by the photodetectors. Alternatively, the first grating may consist of rectangular portions arranged in the X- and Y-direction in a matrix form.
