Title |
Pulsed Schlieren system for visualizing beams from phased-array HIFU applicators |
Date |
2007 |
Description |
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 stop, and a 12-bit CCD camera (1035 x 1317 pixels). The laser is synchronized to the driving electronics of the transducer but its pulse is delayed, effectively freezing of the acoustic wavefronts in the imaged space. |
