A beam projector which is controlled to alternately transmit rectangular cross-sectional beams substantially parallel to a projection axis, wherein the beams are respectively pulse modulated over a correspondingly distinct pulse rate frequency range to supply yaw and pitch information and are respectively scanned in a direction correspondingly orthogonal to its cross-sectional length. The size format of the beam cross-sections and the angle of the scan are controlled according to a predetermined time variable function. In a first time period, the largest...
A controlled beam projector for alternately generating two orthogonally oriented and orthogonally scanned rectangular cross-section beams of radiation, comprising: means for selectively generating a plurality or orthogonally oriented beams of radiation; means for selectively energizing said generating means to alternately generate orthogonally oriented beams of radiation having a corresponding predetermined cross-sectional area; means connected to said energizing means for modulating respective alternately generated beams at pulse rates which vary over r...
