Abstract:
1. A method of measuring transverse sensitivity of a sensor for detecting acceleration comprising: applying vibration acceleration to at least one sensor which is fixed, via a jig, on a uniaxial vibration generator for generating rotational vibration motion, and which detects acceleration based on said rotational vibration motion; calculating transverse sensitivity from an output value of said sensor obtained by the application of the vibration acceleration, and from a measurement value of input acceleration to said sensor obtained by measuring the input acceleration with a measuring instrument independent of said sensor during the application; and generating a sensitivity matrix based on the transverse sensitivity, the calculated transverse sensitivity being an element of the sensitivity matrix, wherein the application is carried out in a state in which a coordinate axis of a coordinate system of a space defining the input acceleration to said sensor is aligned with a direction of a rotational axis of the vibration by adjusting said jig, the coordinate axis corresponding to a sensing axis of said sensor.
