Example embodiments include a motion mechanism that can be coupled between the main body of an unmanned movable object and the optoelectronic scanning module. The motion mechanism can include, e.g., a spinning device and a tilting device. The spinning device can be operable to rotate the scanning module relative to the main body about a spin axis. The tilting device can be operable, e.g., in response to a tilt angle input, to rotate the scanning module about an additional axis that is transverse to the spin axis. Further example embodiments include an orientation sensor installed on the main body of the unmanned movable object. Some embodiments also provide a controller that is configured to receive an orientation signal from the orientation sensor and, based at least in part on the orientation signal, determine a tilt value for the tilt angle input for the tilting device in the motion mechanism.

Laser radar scanning and positioning mechanisms for UAVs and other objects, and associated systems and methods

An apparatus includes a light source configured to emit light, a beam shaper configured to project the light to substantially surround the apparatus in a plane and onto an object in the plane, and a receiver configured to project the light reflected from the object in the plane to an image sensor. A distortion parameter of the receiver in conjunction with a difference between the emitted light and the reflected light detected at the image sensor is indicative of at least one of a direction or a distance of the apparatus relative to the object.

Circular light source for obstacle detection

Introduced here are techniques for implementing a comparator-based LIDAR system with improved components, such as an improved high-speed comparator circuit, to acquire depth information from the surroundings of an unmanned moving object (e.g., a UAV). In various embodiments, the LIDAR system includes an amplifier module with different configurations of anti-saturation circuitry. The LIDAR system may further include various feedback control mechanisms for noise interference reduction and timing measurement compensation including, for example, dynamic gain adjustment of the photodetector module, and/or dynamic adjustment of comparators' thresholds. Among other components, the disclosed comparator circuit can provide the LIDAR system with a wide dynamic range, preventing large signal amplification saturation while also providing sufficient magnification of small signals.
