Abstract: A component is fabricated in a powder bed by moving a laser array across the powder bed. The laser array includes a plurality of laser devices. The power output of each laser device of the plurality of laser devices is independently controlled. The laser array emits a plurality of energy beams from a plurality of selected laser devices of the plurality of laser devices to generate a melt pool in the powder bed. A non-uniform energy intensity profile is generated by the plurality of selected laser devices. The non-uniform energy intensity profile facilitates generating a melt pool that has a predetermined characteristic.

Abstract: A system includes a light emitting unit, a front mirror, a rear mirror, an imaging unit and a processor. The light emitting unit is configured to emit a collimated light beam. The front mirror is configured to reflect part of the collimated light beam to produce and project a front focused ring of structured light to an object to obtain a front reflected ring of light, and configured to allow part of the collimated light beam to pass by. The rear mirror is positioned downstream of a light transmitting path of the front mirror. The rear mirror is configured to reflect at least part of the collimated light beam passing by the front mirror to produce and project a rear focused ring of the structured light to the object to obtain a rear reflected ring of light.

Abstract: A lens system includes a tube lens and a lens assembly, with the tube lens disposed between an optical sensor and the lens assembly. The lens assembly is disposed between the tube lens and an imaged object. In order to solve the problem of some lens systems having focal lengths that are shorter than the working distances of the lens systems, one aspect of the inventive subject matter described herein provides the lens assembly with a negative lens and plural positive lenses. A first positive lens is located between a second positive lens and an imaging plane, the second positive lens is located between the first positive lens and the negative lens, and the negative lens is located between the second positive lens and the tube lens.
