ABSTRACT:
The present invention provides a laser rotating and irradiating system, having a main unit, which comprises a light emitting means, a scanning means for rotating a laser beam for scanning, a reflection light detecting means for detecting reflection light from an object reflector, an angle detecting means for detecting an angle of an irradiating direction of the laser beam, a scanning control unit for controlling a scanning range of the laser beam based on detection results of the angle detecting means and the reflection light detecting means, and a rotation control unit for driving a scanning motor within the scanning range.
