Abstract: Methods for detecting irregularities in a composite structure can include obtaining temperature data from a surface of the composite structure while the composite structure undergoes a thermal change. An irregularity in the composite structure is detected based on the temperature data.

Abstract: Methods for detecting irregularities in a composite vehicle can include cooling the composite vehicle to a substantially uniform first temperature, heating a surface of the composite vehicle to a second temperature that is higher than the first temperature, and obtaining temperature data from the composite vehicle after the surface has been heated. An irregularity in the composite vehicle is detected based on the temperature data.

Abstract: A modular LIDAR system may be formed of multiple LIDAR components. Each LIDAR component may include a laser emitter and a laser detector configured in a frame. Multiple LIDAR components may be arranged on a rotatable swivel housing. The rotatable housing may rotate about a first axis that is perpendicular to a plane defined by a mounting base. The multiple LIDAR components may be aimed outward from the swivel housing at different directions, which may range up to 90 degrees or up to 180 degrees in separation in some embodiments. When the rotatable housing is rotated completely around the first axis, the multiple LIDAR components may scan a first field of view of 360 degrees around the first axis and may scan a second field of view of substantially 180 degrees about a second axis. The modular LIDAR system may be implemented with an aircraft for navigational purposes.
