Binary Pressure Sensitive Paint
Another area of interest has been the measurement of surface pressure in low-speed wind tunnels. Binary PSP systems are used in low-speed wind tunnel environments where pressure gradients are small and error sources are more significant. Model shift between reference condition and loaded condition, variation in paint thickness, lamp instability, and temperature are significant sources of error in PSP data. Binary PSP mitigates many of these error sources by employing a second probe into the paint layer, known as the reference probe. This reference probe is used to ratio out the effects of these errors producing high quality PSP pressure maps at low speeds.

Famous quotes containing the words pressure, sensitive and/or paint:
“Osteopath—One who argues that all human ills are caused by the pressure of hard bone upon soft tissue. The proof of his theory is to be found in the heads of those who believe it.”
—H.L. (Henry Lewis)
“In the true sense one’s native land, with its background of tradition, early impressions, reminiscences and other things dear to one, is not enough to make sensitive human beings feel at home.”
—Emma Goldman (1869–1940)
“For a painter, the Mecca of the world, for study, for inspiration and for living is here on this star called Paris. Just look at it, no wonder so many artists have come here and called it home. Brother, if you can’t paint in Paris, you’d better give up and marry the boss’s daughter.”
—Alan Jay Lerner (1918–1986)
