  • First Online:
Pressure and Temperature Sensitive Paints

Part of the book series: Experimental Fluid Mechanics ((FLUID))

Abstract

This chapter describes the intensity-based methods that are widely used in PSP and TSP measurements. A generic camera-based system is first described, which includes illumination sources, optical filters, digital cameras (CCD and CMOS cameras), and data acquisition and processing units. Then, a generic laser-scanning system is briefly described for PSP and TSP measurements. Furthermore, the basic data processing for the intensity-based methods is described. Uncertainty analysis of the intensity-based methods for PSP and TSP is a major topic of this chapter, including system modeling, error propagation, sensitivity coefficients, total uncertainty, elemental error sources, and measurement limits.
