Abstract
A two-dimensional displacement sensor includes first and second laser units that emit first laser light incident on the surface of the strip-shaped member from a direction intersecting the thickness direction of the strip-shaped member and second laser light incident on the surface of the strip-shaped member from a direction parallel to the thickness direction of the strip-shaped member, a camera that has a light receiving element for receiving light reflected from the surface of the strip-shaped member and measures the amount of displacement of the surface of the strip-shaped member from the reflected light receiving position detected by the light receiving element, an optical element for focusing the reflected light on the light receiving element, and a switching member for switching the laser light to be incident on the surface of the strip-shaped member between the first laser light and the second laser light.
