Abstract: Detectors are situated along a tilted optical axis to receive optical radiation from a work surface. Variations in the received optical power are used to estimate a work surface positional along a work surface axis. The received optical power can be emitted from the work surface and an estimated temperature of the work surface used to adjust the received optical power. One or two single element detectors or a linear detector can be used. A position of a focused spot produced from the received optical power at the linear detector can be used to assess work surface axial position.

Abstract: 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.

Abstract: A method for treating a material comprising: applying energy to a predetermined portion of the material in a controlled manner such that the local chemistry of the predetermined portion is altered to provide a predetermined result. When the material is a shape memory material, the predetermined result may be to provide an additional memory to the predetermined portion or to alter the pseudo-elastic properties of the shape memory material. In other examples, which are not necessarily restricted to shape memory materials, the process may be used to adjust the concentration of components at the surface to allow the formation of an oxide layer at the surface of the material to provide corrosion resistance; to remove contaminants from the material; to adjust surface texture; or to generate at least one additional phase particle in the material to provide a nucleation site for grain growth, which in turn, can strengthen the material.

Abstract: A laser processing system capable of appropriately adjusting a timing to switch a laser output command with respect to the movement of an axis, and improving synchronization accuracy between the movement of the axis and a cutting position. A block remaining time of a block in execution is compared to a predetermined switching time. When the block remaining time is equal to or larger than the switching time, a laser output command of the current block is continued. On the other hand, when the block remaining time is smaller than the switching time, the laser output command to a laser oscillator is switched from the command of the current block to a command of a block subsequent to the current block.
