Method and device for measuring the rotational angle of a rotating object |
摘要 |
<p>The method involves transmitting two linearly polarized light rays (a,b) whose polarization planes are rotated relative to each other. The intensity of the light rays is periodically modulated in phase shifted fashion relative to each other. An independent claim is included for device for measuring rotation angle between two objects.</p> |
