【Abstract】 The method of differential frequency measurement is studied thoroughly. And a new method for static precise measurement of angular displacement is transformed from the method of differential frequency for dynamic transmission error measurement. Then, a new method, named "method of duality for gear and electric wave" to be applied to engineering design of differential frequency circuit, is presented and a combined dual-gear model displacement sensor based on differential frequency measurement is developed.更多还原
