Abstract:
A light ray controller has a circular frustum shape and is fitted in a circular hole of a top board such that its large diameter bottom opening faces upward. The light ray controller transmits a light ray while diffusing the light ray in a ridgeline direction and transmits the light ray straightforward without diffusing the light ray in a circumferential direction. A rotation module is provided under the table. One or more scanning projectors are provided on a circumference around an axis of the light ray controller on the rotation base of the rotation module. One or more scanning projectors are rotated by the rotation module. The controller controls one or more scanning projectors being rotated based on three-dimensional shape data stored in a storage.
