Abstract
New and improved instrumentation, like new and improved wind tunnels, provide capabilities which stimulate innovative research and discovery. During the past few years there have been a number of instrumentation developments which have aided and abetted the acquisition of more accurate aerodynamic data and have led to new physical insights as well. Some of these advances are reviewed, particularly in the area of thin film gages, hot wire anemometry, and laser instrumentation. A description is given of the instruments and/or techniques and some sample results are shown
