Abstract: Methods and apparatus for a sensor system having a structure having a reflective surface, wherein the structure is rotatable about a longitudinal axis. Channels provide respective paths from an entry into the channels to the reflective surface. A shroud selectively block ones of the channels to provide an operational configuration and a calibration configuration.

Abstract: An alignment mechanism to position and focus a lens assembly includes a housing and an eccentric shaft supported by the housing. The eccentric shaft is configured to rotate with respect to the housing. The alignment mechanism further includes a lens assembly having a bracket coupled to the eccentric shaft, and an actuator assembly, coupled to the bracket of the lens assembly and configured to rotate the lens assembly about the eccentric shaft. The alignment mechanism further includes at least one thrust drive nut mounted on the eccentric shaft, the at least one thrust drive nut being configured to move the eccentric shaft and the bracket of the lens assembly in a z-axis direction.

Abstract: A lens mount assembly is configured to support a lens assembly having a lens ring and at least one lens secured to the lens ring. The lens mount assembly includes a ring mount having an annular body with at least two retaining arms that project from the annular body, a flexure configured to be secured to the ring mount, and at least two bellows. Each bellows is configured to be secured to a respective retaining arm of the at least two retaining arms of the ring mount. The at least two bellows further are configured to engage the flexure.
