1. A method of generating a holographic image within an ambient atmosphere air display volume using a columnar laminar flow generation system and a laser projection system, the method comprising:
the columnar laminar flow generation system intaking an input ambient atmosphere air and generating an ambient atmosphere air flow;
the columnar laminar flow generation system combining the input ambient atmosphere air flow with at least one particulate flow using a first laminar flow grid to receive the input atmosphere air flow and generate a plurality of parallel columnar laminar atmosphere air flow streams and a plurality of parallel columnar laminar atmosphere particulate flow streams extending from the first laminar flow grid through the ambient atmosphere air display volume to a second laminar flow grid displaced from the first laminar flow grid, the first laminar flow grid including an array of parallel columnar flow guides, each flow guide including an inlet end receiving at least a portion of the ambient atmosphere air flow or at least a portion of the one or more particulate flows, an outlet end outputting at a first constant flow rate one or more of the plurality of columnar laminar atmosphere air flow streams or one or more of the parallel columnar laminar particulate flow streams, and a hollow center volume extending from the inlet end to the outlet end;
the second laminar flow grid intaking at a second constant flow rate the combined atmosphere air flow and at least one particulate flow through the second laminar flow grid, the second laminar flow grid including an array of parallel columnar flow guides, each flow guide including an inlet end receiving at least a portion of the one or more of the plurality of columnar parallel laminar atmosphere air flow streams or at least a portion of the parallel columnar laminar particulate flow streams, an outlet end outputting at a second flow rate at least a portion of the plurality of columnar parallel laminar atmosphere air flow streams or at least a portion of the parallel columnar laminar particulate flow streams flows, and a hollow center volume extending from the inlet end to the outlet end; and
the laser projection system outputting a plurality of laser beams representative of the holographic image, each of the plurality of laser beams aligned to overlap a section of a single columnar laminar particulate flow within the ambient atmosphere air display volume and each of the laser beams illuminating a target particulate flow within the respective overlapping section of the single columnar laminar particulate flow.
