Abstract
The present invention relates generally to ladar and more particularly to a tilted primary clamshell lens laser scanner for transmitting a generally collimated beam of radiation at a first frequency such that the beam rotates about a central axis so as to form a conical scanning pattern suitable for lidar applications. In addition, the ladar includes a system for transmitting at least one additional collimated beam of radiation at a second frequency at a wider angle then the first collimated beam.
