Embodiments herein provide for improved range response in lidar systems. In one embodiment, a lidar system includes a laser, and a detector. First optics direct light from the laser on a beam path along a first optical axis of the first optics. Second optics image the light from the beam path onto a second plane that is substantially normal to the first plane. The second optics have a second optical axis that differs from the first optical axis. The first and the second optical axes lie in a same first plane. A first line in the first plane intersects a second line in the second plane at an acute angle. The first line is perpendicular to the first optical axis. A spatial filter configured in or near the second plane filters the light from the second optics onto the detector.

Systems and methods herein provide for floating sensors. In one embodiment, a system includes a waterproof housing, an electronics assembly mounted within the waterproof housing, and a wing structure hingeably attached to the waterproof housing and operable to float the system on a water surface. The system also includes a solar panel configured on the wing structure to provide power to the electronics assembly.

Floating sensor

Provided herein are systems and methods for scanning an optical sensor on a platform required to operate within a medium having a different pressure than the internal pressure of the sensor, including both underwater and high-altitude applications. For the case of underwater platforms, portions of the vehicle may be pulled or driven by propulsive forces through the water, whereas other portions of the vehicle may carry the platform for optical scanning, attached and rotationally controlled with respect to the driven portion of the vehicle. The platform may be rotated with respect to the portion that is pulled or driven through the water or other fluid. In some embodiments, that driven portion remains rotationally fixed with respect to the water. Other embodiments of vehicles in different environments may interface with different fluids or gasses and may be driven through the fluids or gases in similar manners.
