| 摘要 |
<p>The present invention provides a non-contact drive belt tension monitoring apparatus for measuring drive belt tension on a drive belt vibrating in response to a stimulus. A coherent light source, associated with the drive belt, generates coherent light which is reflected by a determined region of the drive as reflected coherent light. A light receiver receives reflected coherent light containing vibration information. Attached circuitry processes the output of the light receiver to generate a drive belt tension measurement.</p> |
