Comparison of three different illuminations to image an underwater shockwave.
Shockwave Imaging
In ultra-high-speed applications, such as shockwave imaging, motion blur is typically one of the key factors that reduce the information content of the images. If the camera exposure time is not short enough, or if the output power and brightness of the illumination are not high enough, motion blur cannot be avoided. CAVILUX laser illumination overcomes both of these problems by providing short light pulses of high power and brightness up to repetition rates in the MHz range.
- Clear visibility of shockwaves
- More detailed images as compared to other light sources
- Applicability up to 10 MHz with ultra-high-speed (UHS) version
- E.g. medical applications, combustion in pressure chambers, materials testing
- Recommended products: CAVILUX HF or CAVILUX Smart
