Since 1980’s

with the development of Biochemistry

Photophysics

Computer & Information Technology and Image-processing technology

Pressure-Sensitive Paint(PSP) technique has been widely employed in many engineering fields because of its evident advantages

such as easy to operate

lower cost

noninterference in flow field and wide range of pressure measurement.The contents of this paper including basic theory of luminescence molecules and its application to optical measurement

development of PSP technique

applications of PSP technique both to internal and external flow fields were depicted to exhibit the perspectives of PSP technique.The details of the differences of PSP technique applied to internal and external flow fields

the role of Temperature-Sensitive Paint in PSP measurement

the methods and procedures of PSP technique application were introduced as many as possible.
