Abstract: A powder melting device for an additive manufacturing system is provided. The powder melting device includes at least one laser device configured to generate at least one energy beam for forming at least one melt pool in a layer of powdered material. The powder melting device also includes at least two optical elements configured to dynamically induce beam distortion in the at least one energy beam to modify a beam spot incident on the layer of powdered material. The at least two optical elements are configured to induce at least one of an aspect ratio adjustment of the at least one energy beam, an optical powder redistribution between a periphery and a center of the at least one energy beam, and a rotation of the at least one energy beam.

Abstract: A lens array assembly includes plural lens elements each configured to receive incoming light from one or more light sources. The lens elements include biconic refractive elements on first sides of the lens elements and including diffractive elements on opposite, second sides of the lens elements. The lens elements are configured to change directions of the incoming light received from the one or more light sources such that outgoing light emanating from the lens elements is collimated in a first direction but diverges along a different, second direction.

Abstract: The present approach relates to the synchronization of frame acquisition by a camera with an external event or trigger despite the camera lacking external control or synchronization capabilities. For example, inexpensive and/or consumer grade camera typically lack a control interface to explicitly synchronize with an external trigger event or external device. The present approach allows synchronization of such a camera lacking external synchronization capabilities with an external event or device.

Abstract: Waveguides having improved illumination distribution and output luminance variation and lighting systems utilizing such waveguides are disclosed. The lighting systems generally include a light source which is optically coupled to a waveguide to distribute the light. The waveguides include one or more headlighting reduction regions and one or more output intensity shaping regions that work together to improve the distribution of light and reduce the effects of headlighting. The headlighting reduction regions may be integrated with the output intensity shaping region or may be an independent section.
