摘要： In one embodiment, a lidar system includes a light source configured to emit pulses of light. The lidar system also includes multiple optical links and multiple sensor heads. Each optical link couples the light source to a corresponding sensor head, and each optical link is configured to convey at least a portion of the emitted pulses of light from the light source to the corresponding sensor head. Each sensor head includes a scanner configured to scan pulses of light across a field of regard of the sensor head, where the scanned pulses of light include the portion of the emitted pulses of light conveyed from the light source to the sensor head by the corresponding optical link. Each sensor head also includes a receiver configured to detect at least a portion of the scanned pulses of light scattered or reflected by a target located downrange from the sensor head.

摘要： A method and an apparatus of a powder bed fusion additive manufacturing system that enables a quick change in the optical beam delivery size and intensity across locations of a print surface for different powdered materials while ensuring high availability of the system. A dynamic optical assembly containing a set of lens assemblies of different magnification ratios and a mechanical assembly may change the magnification ratios as needed. The dynamic optical assembly may include a transitional and rotational position control of the optics to minimize variations of the optical beam sizes across the print surface.

摘要： Disclosed is a laser module comprising: a housing having a platform (a - g, h - n); one or more laser sources (303) secured to the platform; optical components to direct radiation from the one or more lasers to an endcap (1505), the endcap being positionally secured to a structure in the platform; an optical fiber (1506) secured inside the housing to the endcap (1505); an epoxy coating applied to a cladding of the optical fiber (1506) inside the housing, wherein a refractive index of the coating is the same or greater than a refractive index of the cladding.

摘要： A multiplexer includes: an output section outputting a beam bundle made of a plurality of laser beams whose F-axis directions are aligned; and an F-axis converging lens causing the beam bundle outputted from the output section to be converged in the F-axis direction. Optical axes of the plurality of laser beams constituting the beam bundle outputted from the output section intersect with each other at a single point without relying on the F-axis converging lens.
