Abstract:
1. A device for measuring dynamic matrix sensitivity of an inertia sensor, comprising: a motion generating machine for inducing a motion including at least one of a translational motion and a rotational motion, wherein a degree of freedom of the motion is N (1≦N≦6, and N is an integer); a unit subject to calibration provisionally fixed on a table of the motion generating machine, constituted by at least one of an acceleration measuring unit, an angular velocity measuring unit and an angular acceleration measuring unit, wherein a degree of freedom of detection is M (1≦M≦6, and M is an integer); output means for fetching an output from the unit subject to calibration; one or more light reflectors; a displacement measuring unit enabled to grasp a multidimensional motion by using a laser interferometer formed by irradiating the one or more light reflectors with laser beams from as many directions; a processing unit for calculating an M×N dynamic sensitivity matrix S displaying means to display or a transmitting means to transmit an output of the processing unit and output of the unit subject to calibration.
