Abstract:

The invention provides a way of positioning the material to be scanned with respect to a mirror that both rotates and translates in order to reflect a scanning beam on the material. A sector of a cylinder has the same axis as the rotating mirror. The material to be scanned is mounted on the top of a flexible plate. The flexible plate may rest flat on a table outside of the area scanned. The flexible plate may then be pushed into the cylinder with the bottom face of the flexible plate in contact with the inner side wall of the sector of the cylinder. When the flexible plate has reached the proper position in the cylinder, the bottom face of the plate of the flexible plate is held in position against the inner wall of the sector of the cylinder by suction, so that scanning may proceed.
