AXIAL VIBRATOR OF RING LASER GYROSCOPE

摘要

PURPOSE: An axial vibrator of a ring laser gyroscope is provided to make the axial vibrator in a compact size and to allow the axial vibrator to be easily attached/detached to/from a mono-block. CONSTITUTION: An axial vibrator(21) of a ring laser gyroscope includes a plurality of elastic bending driving spokes(22), which are radially aligned. An upper plate(23) is positioned on the elastic bending driving spokes(22). A lower plate(25) is positioned under the elastic bending driving spokes(22). A plurality of bolt coupling holes(24,26) is formed in the lower plate(25) in order to couple the lower plate(25) to a base frame by means of a bolt. A plurality of piezoelectric devices is installed on the elastic bending driving spokes(22). The upper plate(23) is aligned in parallel to the lower plate(25). The elastic bending driving spokes(22) are vertically installed with respect to the upper and lower plates(23,25).
