Abstract
A laser instrument and a method for adjusting the laser power is disclosed. The laser instrument includes a laser device which generates a laser beam and a rotating device which moves the laser device back and forth around an axis of rotation between a first turning point and a second turning point. The laser beam generates a laser line between a first end point and a second end point on a target surface. A control device is provided which adjusts the laser power of the laser beam as a function of a rotation angle and/or an angular velocity of the rotating device.
Claims8
A laser instrument, comprising:
- a laser device;
- a rotating device, wherein the laser device is moveable back and forth around an axis of rotation between a first turning point and a second turning point by the rotating device;
- a control device, wherein a laser power of the laser device is adjustable as a function of a rotation angle and/or an angular velocity of the rotating device by the control device;
- a first measuring device, wherein the rotation angle of the rotating device around the axis of rotation is determinable by the first measuring device;
- and
- a second measuring device, wherein the angular velocity of the rotating device around the axis of rotation is determinable by the second measuring device.
A method for adjusting a laser power of a laser beam, comprising the steps of:
- moving a laser device back and forth by a rotating device around an axis of rotation between a first turning point and a second turning point;
- generating a laser line between a first end point and a second end point on a target surface by a laser beam of the laser device;
- and
- adjusting a laser power of the laser beam as a function of a rotation angle of the rotating device;
- wherein the step of adjusting includes reducing the laser power to zero when falling short of a first rotation angle which corresponds to the first end point and which is greater than a rotation angle corresponding to the first turning point and/or when exceeding a second rotation angle which corresponds to the second end point and which is smaller than a rotation angle corresponding to the second turning point;
- wherein a power value of the laser power is zero in a first angle range between the first end point and the first turning point and in a second angle range between the second endpoint and the second turning point.
A method for adjusting a laser power of a laser beam, comprising the steps of:
- moving a laser device back and forth by a rotating device around an axis of rotation between a first turning point and a second turning point;
- generating a laser line between a first end point and a second end point on a target surface by a laser beam of the laser device;
- and
- adjusting a laser power of the laser beam as a function of an angular velocity of the rotating device;
- wherein the step of adjusting includes decreasing the laser power from a first power value to a lower second power value when a preset first angular velocity of the rotating device is fallen short of and increasing the laser power from the second power value to the first power value when exceeding a preset second angular velocity of the rotating device.
