摘要
<p>The optical acceleration sensor is provided with a hollow cylinder (1), where a light beam (2) is passed by a mirrored hollow cylinder. The light beam receives a polygonal spiral shape, and leaves an angle of a hollow cylinder. An output of the hollow cylinder is changed in a time period of light during acceleration (3) of an assembly in an axis of the spiral-shaped light path such that the light beam leaves another angle of the hollow cylinder. The light beam detects the acceleration of the assembly.</p>
