Particle Image Velocimetry (PIV)
Particle Image Velocimetry (PIV) is a whole-flow-field technique providing instantaneous velocity vector measurements in a cross-section of a flow. This technique being a non-intrusive one, allows the application of PIV in high speed flows, boundary layer studies of fluids.

Nano PIV
The new form of PIV--nano-particle image velocimetry (nPIV)--based on total internal reflection fluorescence (TIRF), or evanescent-wave fluorescence, to study flows in the interfacial region next to the channel wall with a spatial resolution normal to the wall of 100-300 nm.

Laser Doppler Velocimetry (LDV)
Laser Doppler Velocimetry (LDV) is a technique used to measure the instantaneous velocity of a flow field. This technique, like PIV is non-intrusive and can measure all the three velocity components.

Pressure Sensitive Paint (PSP)
Pressure sensitive paint is an optical method to obtain the pressure on an object surface without instrumenting the object. The surface is coated with a paint containing luminophore molecules(florescent or phosphorescent) and illuminated with light source emitting light of of sufficient short wavelength to excite the luminophore.

Thermal Imaging
Thermal Imaging refers to the process of capturing the heat from an object, which is undetectable to the human eye, and transforming it into an image that can be viewed. Primarily used for night-vision surveillance applications.
