摘要： Techniques are disclosed for an improved boresighting apparatus and related method for boresighting a light source to an imaging sensor, and for an improved material to be used in a target object in such a boresighting apparatus. For example, an apparatus for use in boresighting may include a catadioptric element and a target object, where the catadioptric element is configured to focus a laser beam from the light source and also to collimate light emitted from the target object at a different wavelength than the laser beam to be detected by the imaging sensor for indicating the location of the focused laser beam. The target object may, for example, comprises a fluorescent optical material doped with one or more optically active ions to absorb light having the wavelength of the laser beam and emit light in one or more wavebands detectable by the imaging sensors.

摘要： Plastic parts are welded in a laser welding system. An infrared laser source in a laser chamber is controlled by a controller using closed-loop feedback control with a corrected feedback signal that is compensated for background infrared radiation in the laser chamber. Prior to the infrared laser source being turned on, the controller senses with the optical sensor an intensity of background infrared radiation in the laser chamber. Once the laser is on, the controller senses with the optical sensor an intensity of infrared laser radiation in the laser chamber. The controller calculates the corrected feedback signal by subtracting the intensity of the background infrared radiation sensed when the infrared laser source was off from the intensity of the infrared laser radiation sensed when the infrared laser source is on.

摘要： A laser cutting device includes a laser oscillator, a cutting nozzle configured to irradiate a work with laser light so as to cut the work, and a controller configured to control the laser oscillator and a drive unit configured to move the cutting nozzle. The controller includes a laser output control unit, a diagnosis performance determination unit configured to determine, when the laser oscillator satisfies a predetermined operation condition, based on a cutting program, whether or not the laser oscillator is diagnosed, and a diagnosis function performance unit configured to issue a laser output command for diagnosis of the laser oscillator to the laser oscillator. When the diagnosis performance determination unit determines that the laser oscillator is diagnosed, the diagnosis performance determination unit outputs the laser output command for diagnosis to the laser oscillator.

摘要： A method for producing a three-dimensional component by means of a laser melting process, in which the component is produced by consecutively solidifying individual layers made of building material by melting the building material, wherein said building material can be solidified by the action of radiation, wherein the melting area produced by a punctiform and/or linear energy input is detected by a sensor device and sensor values are derived therefrom in order to evaluate the component quality. The sensor values detected in order to evaluate the component quality are stored together with the coordinate values that locate the sensor values in the component and are displayed by means of a visualization unit in two- and/or multi-dimensional representation with respect to the detection location of the sensor values in the component.

摘要： Apparatus for determining geometrical parameters of a laser beam includes an optical system, a device for output coupling radiation, a beam diagnostic device, and a reflector element. The optical system focuses the laser beam into a processing region. The device for output coupling radiation couples out radiation that runs through the optical system in a direction opposite to a direction of the laser beam. The reflector element has a first surface which is partially reflecting and curved, where the curvature is equal to a mean curvature of a wave front of the laser beam in a positioning region of the reflector element.

摘要： This shaping apparatus is equipped with: a movement system which moves a target surface; a measurement system for acquiring position information of the target surface in a state movable by the movement system, a beam shaping system that has a beam irradiation section and a material processing section which supplies a shaping material irradiated by a beam from beam irradiation section; and a controller. On the basis of 3D data of a three-dimensional shaped object to be formed on a target surface and position information of the target surface acquired using the measurement system, the controller controls the movement system and the beam shaping system such that a target portion on the target surface is shaped by supplying the shaping material while moving the target surface and the beam from beam irradiation section relative to each other.
