Abstract
An image-capturing device for forming an image of an uneven surface of an object includes a light-guiding plate that has a detection surface for contacting the uneven surface of the object, a pair of lateral surfaces, one of which receives incident light from a primary light source such that the incident light is able to illuminate the uneven surface of the object on the detection surface, a total internal reflection surface opposite to the detection surface for reflecting totally light scattered by the uneven surface of the object, and a reflector surface connected to and forming a tilt angle with the total internal reflection surface. An imaging system is disposed to receive the light that was reflected by the reflector surface and that exits the light-guiding plate so as to form the image of the uneven surface of the object.
