Imagination is more important than knowledge. For knowledge is limited to all we now know and understand, while imagination embraces the entire world, and all there ever will be to know and understand.
—Albert EinsteinOne of the notable contributions of this laboratory is the development of Particle Image Velocimetry, which measures the synoptic velocity field in selected planes of a flow. The technique is routinely used to produce two-dimensional velocity maps of low speed subsonic and high speed supersonic flows sand is currently being extended to:
Each test facility at FMRL is equipped with extensive state-of-the-art optical diagnostics. Some of the primary hardware includes 4 Nd:Yag pulsed lasers, 5W and 15W Argon-Ion CW lasers and several low power He:Neon lasers. Digital Image Processing facilities include two IBM RISC 6000 stations and several microcomputers. As a by-product a technique has also been developed to measure instantaneous density fields using the correlation of electronically recorded laser speckles
