Abstract:
1. A laser irradiating system, comprising a light source for emitting a laser beam in elliptical shape, a light source holder for holding said light source, a base for rotatably supporting said light source holder, a first driving unit for rotating said light source holder, a deflecting optical means for deflecting the laser beam from said light source in a direction perpendicular to an optical axis, a rotator holder for holding said deflecting optical means and being rotatable around the optical axis of said light source, a cylindrical lens being arranged so that a center of said cylindrical lens is aligned with said optical axis and the laser beam from said deflecting optical means enters perpendicularly to the optical axis and for diffusing the transmitting laser beam to a fan-shaped laser beam, a control unit for controlling said first driving unit and a receiver for receiving a signal for remote-control operation, wherein an irradiating direction of said fan-shaped laser beam can be operated in remote control operation by said control unit based on a command signal received by said receiver.
