Features of the OptiSon® Beam Analyzer
Quantitative
The OptiSon® Beam Analyzer quantifies beam plots, focal distances
and total power from a single image. Power measurements correlate
to radiation force balance and hydrophone - as does tomographic
reconstruction for intensity. It has higher spatial resolution than
mechanical scanning and is invulnerable to high intensities or rough
handling
Eliminates Standing Waves
Unlike scanning methods such as acoustic microscopy, laser interferometry
and hydrophone surveys, the sensor in OptiSon® does not invade
or disturb the acoustic field. Instead, acoustic waves are detected
by Raman-Nath diffraction of light in a transparent medium.
Schlieren Visualization Advantage
See the visual advantage
- Visualizes, maps and measures acoustic fields in seconds or
minutes instead of hours or days. Now you can achieve control
of project timing and costs, gain a more comprehensive and confident
understanding of the system and transducer performance, eliminate
the tedium of testing and provide timely results.
- Reveals radiation ordinarily missed by a hydrophone survey.
- Provides instant identification of non-uniform wave formation
at different frequencies. This enables diagnosing uneven thickness
of piezo-electric materials or matching layers.
- Maps whole acoustic field in linear or log (dB) scale which
can be displayed in black & white or pseudo-color.
- Easily generates one, two or three dimensional maps of power
or intensity and instantly reveals heating of transducer surface.
- Unprecedented Dynamic Range
- The proprietary optical design generates images with a dynamic
range never possible with previous schlieren designs.
- 3-D Tomographic Imaging
- Tomographic reconstruction software is available for full 3D
pressure and intensity maps throughout the acoustic field. This
allows automatic determination of ISPTA and other parameters of
interest.
Flexible modes of Operation
Both pulsed and continuous wave operations are available in one
system. This allows transducer testing in all modes of operation
- by itself or connected to the imaging or therapy system. Pulsed mode
(AVI movie) can be used
in single frequency or broadband excitation to study time dependent
effects. Continuous wave operation allows observation of the entire
beam at once (e.g., pressure or intensity maps).
Time Domain Measurement
The OptiSon® Beam Analyzer can accurately pinpoint the focal
spot and the beam axis. A single test point is required for time
domain measurements by hydrophone thus reducing test time and improving
productivity. Hydrophone immersion is also minimized, thus extending
its usual life.
Computer Interface
Images are available in standard video (NTSC or PAL) for capturing
in the frame grabber, which is interfaced to a high end PC.
Rugged, Mobile and Compact
Due to the use of enclosed, folded optics, the OptiSon® Beam
Analyzer is rugged, mobile and dust free. It is available from desktop
to desk size systems.
