Abstract
Provided is a contactless displacement sensor based on a flexible photoelectric nanofilm. The displacement sensor is fixed on a mid-span surface of a bridge; a laser light source is arranged under the displacement sensor, and after the has a deflection, the displacement sensor is displaced along with the bridge, resulting in a corresponding change in an output current; the change of a laser transmission distance, namely the deflection of the bridge, can be obtained through back calculation according to an output current signal. Compared with other traditional deflection measuring devices, the contactless displacement sensor based on a flexible photoelectric nanofilm has the advantages of a simple structure, a high measuring precision, a high response speed, a wide in application range, being capable of achieving real-time automatic measurement and the like.
