Abstract
A shape measurement apparatus includes: a linear light source that includes a superluminescent diode and applies linear light spreading in a width direction of the strip-shaped body to a surface of the strip-shaped body; a screen on which reflected light of the linear light off the surface of the strip-shaped body is projected; an area camera that captures an image of the reflected light of the linear light projected on the screen; and an arithmetic processing apparatus that calculates the surface shape of the strip-shaped body using the captured image of the reflected light of the linear light captured by the area camera.
