lens or rotating mirror means to produce a single or dual illuminated plane of light 73 74 coexisting spatially parallel to or on top of the image on cloud 58 this interactive process is described more clearly below 0065 fig9 a describes the microenvironment generation process in order to deliver a high degree of uniformity to the laminar airflow stream protecting the cloud thereby improving image quality dramatically over existing protective air curtains a multistage venting or baffling arrangement of one or more chambers or baffles vents or meshes of varying sizes and shapes diminishes micro variant changes in temperature and velocity between the microenvironment and cloud thereby minimizing friction and cloud breakdown thereby improving image quality drastically over existing art the surrounding ambient air or exhausted air 198 from the heat exchanger passes through means to move this air such as by an axial tangential fan or blower 199 housed within an enclosure 200 with sidewalls air is mixed into a first stage equalizing chamber 201 to balance air speed and direction within air space 202 in enclosure 200 subsequently the air passes through a linear parallel baffle or vent 203 of length and cell diameter size determined by the reynolds equation.
