Conventional Calibration

Conventional calibration method of an accelerometer does not take account of the direction gap between the package and the internal sensors. The gap causes sensitivity error and crosstalk of other axis acceleration. These errors prevent to calculate accurate input acceleration. This study proposes a new calibration method which provides actual sensor directions and individual sensitivities. Accelerometers have been widely used in the last 10 years. Now they are embedded in smartphones, controllers of game machines and so on. This article regards an accelerometer as a package which is embedded several internal acceleration sensors. Recently, an MEMS 3-axis accelerometer is popular for industrial use. The calibration methods of the accelerometers are defined in industrial standards, represented by ISO.
