Abstract: A light detection and ranging system includes synchronously scanning transmit and receive mirrors that scan a pulsed fanned laser beam in two dimensions. Imaging optics image a receive aperture onto an arrayed receiver that includes a plurality of light sensitive devices. Adaptive methods dynamically modify the size and location of the field of view as well as laser pulse properties in response to internal and external sensors data.

Abstract: The embodiments described herein provide improved techniques for laser welding. These techniques can provide improved weld strength while reducing the potential for damage at the welding surface. In general, the techniques use a mask to selectively block a portion of the laser beam during welding. Specifically, the mask is made to include at least one laser light blocking feature and at least one laser light passing feature. The mask is positioned to be in contact with the plastic bodies that are to be welded together, with the laser light blocking feature and laser light passing feature proximate to the area that is to be welded. Then during welding the laser beam is operated to simultaneously impact the laser light blocking feature and pass through the laser light passing feature.

Abstract: A light detection and ranging system includes synchronously scanning transmit and receive mirrors that scan a pulsed fanned laser beam in two dimensions. Imaging optics image a receive aperture onto an arrayed receiver that includes a plurality of light sensitive devices. A phase offset may be injected into a scanning trajectory to mitigate effects of interfering light sources.
