Abstract: A lidar system includes one or more light sources configured to generate a first beam of light and a second beam of light, a scanner configured to scan the first and second beams of light across a field of regard of the lidar system, and a receiver configured to detect the first beam of light and the second beam of light scattered by one or more remote targets. The scanner includes a rotatable polygon mirror that includes multiple reflective surfaces angularly offset from one another along a periphery of the polygon mirror, the reflective surfaces configured to reflect the first and second beams of light to produce a series of scan lines as the polygon mirror rotates. The scanner also includes a pivotable scan mirror configured to (i) reflect the first and second beams of light and (ii) pivot to distribute the scan lines across the field of regard.

Abstract: Methods of reef construction are disclosed that include exposing a man-made scaffold to environmental conditions such that bivalve organisms grow on the man-made scaffold for a duration sufficient to create a scaffold having two generations of bivalve attachment. Certain methods involve moving the biologically accreted scaffold to a second location to serve as a reef or breakwater after substantial growth of bivalve organisms has occurred.

Abstract: Structures constructed from an artificial material facilitate the setting and growing of oysters, other mollusks, and other organisms for the purposes of food production, artificial reefs/breakwaters, and the like. The artificial material is a composite that acts as both an attractant and nutrient environment for mollusks and other aquatic organisms. The binder for the composite material includes both cement and an organic material. The organic material is selected to attract and feed the aquatic organisms.

Abstract: An apparatus and method of reducing the effects of hydrodynamic forces of waves and water currents in coastal environments (e.g., oceans, and coastal, river, lake, and reservoir banks). The apparatus is an oysterbreak having two basic designs adapted to allow for the attachment of oysters and other bio-fouling marine organisms, using the least amount of material. In one embodiment, the oysterbreak comprises a support structure and plurality of slats (i.e., relatively planar sections or surfaces) having growth layers made from tubing coated with a material capable of inducing aquatic sessile organism attachment and growth. In another embodiment, the oysterbreak comprises a plurality (e.g., two, three, four, five, six, etc.) of growth layers of regular polygonal-shaped members made from a material capable of inducing aquatic sessile organism attachment and growth that when stacked, form a relatively portable, breakwater module.
