Abstract

See full text

A beam steering device includes a housing and a transceiver that emits and receives light beams through at least one opening in the housing. A rotator includes a cylindrical body rotatably mounted within the housing axially between the transceiver and the at least one opening. A wedge-shaped prism is secured within the body and includes a first surface extending perpendicular to the axis and a second surface extending transverse to the axis. An encoder member and a drive member are provided on an outer surface of the body. Sensors are mounted to the housing to sense the encoder member and provide an encoder signal indicative of a rotational position of the prism about the axis. At least one drive element is mounted to the housing and applies force to the drive member to rotate the body and prism about the axis for steering light beams propagating through the prism.
