GYRO SENSOR CORRECTION METHOD USING SIN CIRCURLATION INPUT OF RATE TABLE

摘要

PURPOSE: A gyro-sensor correcting method using a sinusoidal rotation of a rate table as an input is provided to easily obtain a correction value by using a sine wave type input to create a Lissajous graph for comparing input frequency and output frequency. CONSTITUTION: A gyro-sensor correcting method using a sinusoidal rotation of a rate table as an input is as follows. A gyro sensor is fixed on a rate table(10). The rate table is vibrated with a sine wave type input frequency to create an input frequency for the gyro-sensor(20). A sine wave type output frequency for the gyro-sensor from the input frequency is obtained(30). A Lissajous graph is drawn from the ratio between the input frequency and the output frequency to estimate size and phase(40). The estimated size and a correction value are inputted to the gyro-sensor(50).
