Title:
METHOD OF MEASURING LATERAL SENSITIVITY OF SENSOR FOR DETECTING ACCELERATION, AND ACCELERATION MEASURING METHOD
Document Type and Number:
WIPO Patent Application WO/2005/095998
Kind Code:
A1
Abstract:
Lateral sensitivity in a sensitivity matrix of an acceleration sensor is obtained by a single-axis vibration table. A cubic block (6) on which an acceleration sensor (5) is installed such that the direction of X-axis, defined on a table (12) on the upper part of a single-axis vibration table (11) relative to the acceleration sensor (5), coincides with the direction of vibration of the table (12) of the vibration table is fixed, and the table (12) is vibrated in this state to measure acceleration. In the same way as the measurement of main-axis sensitivity, lateral sensitivity Szx relative to X-axis is obtained based on the measurement result from the acceleration sensor (5) and on the measurement result of a measuring device independently measuring the motion of a surface of the table (12). The cubic block on which the acceleration sensor (5) is installed such that the direction of Y-axis, similarly defined on the on the table (12) relative to the acceleration sensor (5), coincides with the direction of vibration of the table (12) is fixed, and lateral sensitivity Szy relative to Y-axis is obtained.
