An Agile-Beam Laser Array Transmitter (ABLAT) uses an array of emitters and an array of lenses to project electromagnetic beams over a wide angular coverage area in the far field. Differences in the separation pitches of the two arrays allows the ABLAT to project beams to contiguous and/or overlapping positions, depending on the ratio of the separation pitches and the lens focal length. Compared to other beam steering technology, the ABLAT is a smaller, lighter, and more efficient means of projecting beams over wider angular coverage areas. Various embodiments can be used in any beam steering application, including, but not limited to: free-space optical communications; light detection and ranging (lidar); optical scanning (e.g., retinal or bar-code scanning); display projection; image capture; optical character recognition; scanning laser microscopy; non-destructive testing; printing; facsimiles; map making; web inspection; color print processing; phototypesetting and platemaking; laser marking; material processing; DNA analysis; and drug discovery.
