Abstract
A three-dimensional inclination angle calculation circuit is provided. The three-dimensional inclination angle calculation circuit includes: X-axis, Y-axis, and Z-axis vibration sensors which change X-axis, Y-axis, and Z-axis electrostatic capacitances according to three-dimensional positions of a measured plane with respect to a reference plane, respectively; X-axis, Y-axis, and Z-axis position value acquisition units which acquire X-axis, Y-axis, and Z-axis position values corresponding to the X-axis, Y-axis, and Z-axis electrostatic capacitances, respectively; and an inclination angle calculation unit which calculates an inclination angle of the measured plane with respect to the reference plane based on the X-axis, Y-axis, and Z-axis position values. Accordingly, it is possible to very easily calculate an inclination angle according to a three-dimensional position of a to-be-measured apparatus by using an existing vibration sensor.
