What is Pressure Sensitive Paint?
Pressure-Sensitive Paint (PSP) is a surface coating that utilizes luminescence to measure static pressure on the surface.
The coating is applied with common spray-painting techniques. The cured paint is illuminated with a short-wavelength (< 530 nm) source, and the surface image is observed through a long-pass (> 550 nm) optical filter. Variations in intensity represent variations in air pressure on the surface; areas darken as the pressure increases. Typically, the image is acquired with a digital camera to enhance the measurement sensitivity and accuracy and is processed with false color for clarity. A very high resolution, two-dimensional map of the air pressure can be achieved with this technology.
