Abstract: A flexible optical measuring device comprises an optical distance measuring module, an optical fiber adapter and an optical coupling module. The optical distance measuring module comprises a light source, an optical receiver and a computing unit. The optical fiber adapter is disposed and connected between the optical distance measuring module and the optical coupling module. The optical coupling module comprises a first optical fiber, a two-in-one optical coupler, a detector and a second optical fiber. A measuring beam is emitted from the light source and reaches the detector. The measuring beam then passes through the detector to the object and forms a reflected beam which is reflected back to the detector, then enters the second optical fiber and passes through the optical receiver and the optical receiver outputs a measurement signal. The computing unit calculates the distance between the object and a terminal of the detector accordingly.

Abstract: The present invention relates to a method for measuring cracks remotely and the device thereof. First, multiple laser spots with known a shape are projected onto a remote wall and beside a crack. Then, by using geometric calculations, the relative coordinates of the laser spots on the wall and the real distance can be given and used as the reference length of the crack. Next, a camera is used for taking a picture of the remote crack along with the laser spots; the image identification technology is used for calculating the relevant parameters of the crack. Thereby, to acquire the parameters of the crack, a user needs not to be present at the site for measuring at a short distance or placing a reference object, and thus providing safety and convenience.
