PURPOSE:To reduce the size and cost of a device by spectrally dividing one laser light sources and using the divided sources successively. CONSTITUTION:A laser beam projected from a laser light generator 1 which is attached with a collimator lens system in a beam outlet and projects the laser beam of a small diameter is reflected by a reflector 3 attached to the shaft of a rotary actuator which can be controlled in positioning. This reflected beam enters an optical fiber incident part 5 which introduces the laser light to an optical fiber. The many optical fiber incident parts are disposed in the positions equidistant from the axis of rotation of the reflector 3 and the laser beam is successively projected from the optical fiber incident parts disposed in the necessary positions by positioning and controlling the reflector successively. The size of the device is thereby reduced. |
