An IR-absorbing tracer gas when viewed against a warm background with an infrared short wave-band camera appropriately filtered can be used for detecting and recording the air turbulence caused by objects in laminar air streams in cleanroom environments. Air flow turbulence patterns in wind tunnels and from product prototypes have also been sucessfully recorded.
