Scanners,Photocopy and Laser Printer
Scanner Scanner OperationThe Cyberware 3D Scanners are designed to scan a wide variety of objects in many configurations. The following sections describe how the scanners work and how they are controlled. Theory of OperationThe scanner operates on the principle that light in a straight line, reflected off an object, can be viewed at a different angle to reveal a profile of the surface. The greater the angle between the light source and the viewing point, the more pronounced the description of the shape; however, the risk of a given surface being in shadow also increases. The scanner uses a plane of laser light which can be distinguished from most ambient light, and has two viewing points positioned at equal angles on both sides of the light source. A beam splitter (one-way mirror) is used to overlay the two images, so that if one side is shadowed, the other will normally contain the data. A system of mirrors inside the scanner enables the optics to be contained in a smaller space than...
