Planar laser-induced fluorescence of hydroxyl radicals has been performed in a reacting boundary layer with emphasis on resolving the complications of performing these measurements in the vicinity of a wall. Excitation of the (1,0) band of the A/sup 2/..sigma..--X/sup 2/Pi transition at 282 nm coupled with detection of the fluorescence from the (1,1) and (0,0) bands near 310-nm minimized interference due to scattered light from the flow apparatus. A silicon intensified target detector provided 2-D images of hydroxyl radical concentration in the reacting boundary layer enabling visualization of ignition. Results are shown for the ignition of ethane--air mixtures over heated quartz or platinum surfaces highlighting the utility of the technique.
