Abstract: A light detection and ranging (LiDAR) system includes light sources configured to generate separate beams of light, a lens array configured to receive the separate beams of light from the light sources and to collimate the separate beams of light into collimated outgoing light that is directed toward an examined area of interest, a light sensitive detector configured to sense reflection of at least part of the collimated outgoing light, and one or more processors configured to determine a distance to one or more objects off which the at least part of the collimated outgoing light was reflected toward the light sensitive detector. The one or more processors are configured to determine the distance based on the reflection of the at least part of the collimated outgoing light.

Abstract: A laser navigational system for a vehicle having a lighting assembly configured for emission of light. A lens array assembly receives incoming light from the lighting assembly and changes the direction of the incoming light received from the lighting assembly such that the outgoing light emanating from the lens array assembly is collimated in a first direction but diverges along a different, second direction. A scanning unit aligns with the lighting assembly to direct the collimated beam in two orthogonal directions. The lighting assembly, the lens array assembly and the scanning unit are configured to direct the light to form a visual beacon that guides navigation of the vehicle to a location.

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: 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: A light source assembly for use in a display device used in conjunction with night vision gear is provided. The light source assembly includes a light emitting diode configured to generate light comprising visible light and does not emit near IR light. A phosphor body configured to absorb the blue light and emit white light which does not contain near IR. The phosphor body prevents near IR light c from saturating the night vision gear.
