Abstract: Motors for driving multi-element optical scanning devices and associated systems and methods include an exemplary optical system. The optical system includes at least one optical element positionable along an optical path to receive radiation, with the at least one optical element having an opening therethrough; a shaft extending through the opening; at least one bearing operably coupled to the shaft; and a motor operably coupled to the at least one optical element to rotate the at least one optical element.

Abstract: Aircraft door (1) including a safety latch (7) having a first locking element (8) and a complementary second locking element (9) which is movable; a link (11) having at least one electroactive polymer portion (13) and adapted to take up: a lock position in which the electroactive polymer portion (13) is supplied with power and the movable second locking element (9) is engaged with the first locking element (8); and an unlock position in which the electroactive polymer portion (13) is not supplied with power and the movable second locking element (9) is kept away from the first locking element (8); a control unit (16) having a power supply (26) for the electroactive polymer portion (13).

Abstract: Small bearings for multi-element optical scanning devices and associated systems and methods include an exemplary LiDAR system. The LiDAR system includes a laser transceiver having a laser emitter and a laser receiver, the laser emitter being positioned to emit laser light along an optical path; a collimating element and at least one optical element positioned along the optical path, the at least one optical element having an opening therethrough; a shaft extending into the opening; and a bearing positioned to rotatably support the at least one optical element relative to the shaft.

Abstract: Ranging device includes a transmission assembly configured to emit an optical pulse sequence; a reception assembly configured to receive at least part of the optical pulse sequence reflected back by an object; an optical path changing element configured to combine transmitting optical path of the transmission assembly and reception optical path of the reception assembly; a collimation element configured to collimate transmitting light beam of the transmission assembly and converge the at least part of the optical pulse sequence reflected back by the object to the reception assembly; and a fixing assembly configured to fix the transmission assembly, the reception assembly, the optical path changing element, and the collimation element to each other.
