 | Christensen, Douglas A. | Pulsed Schlieren system for visualizing beams from phased-array HIFU applicators | We have assembled a Schlieren system for imaging the beam patterns from HIFU transducers in water to verify the desired beam focusing and direction. It consists of a high power (65 mW) short-pulse (as short as 2 ns) laser emitting at 658 nm, a beam expander/spatial filter, water tank, 400 Jim round ... | Ultrasound beam patterns; Pulsed laser; Wavefronts | 2007 |
