Flicker- and Reflection-free Multi-light Illumination for previously installed devices and as part of new systems
Event: Vision 2018
Dates: 06 - 08 November 2018
Location: Stuttgart, Germany
Hall: 1, Booth #: 1H72
It is not possible to create a pearl's image in conventional light without causing specular light reflections. Like other objects with curved shapes and high luster, it reflects both direct and diffused light beams.
The multi-light image of this nicely coloured pearl is free from overexposure.
Flicker-free multi-light: key features and benefits
- Several high-speed LED lighting sections are turned on/off one by one in synchro- nization with the capture of frames.
- The sets of frames are integrated into a clear image without manipulating an object.
Images free from overexposure make possible:
robust defects detection (those seen from one direction only)
examination of details beneath glossy/shadow areas.
- Flawless video stream is instant.
Curved surfaces. Typical lighting arrangements result in specular reflections at all sample orientations. Multi-light reveals a fine surface structure and internal details.
Polished surfaces and transparent objects. Both direct and diffused modes create reflections and refractions which obscure internal features. Multi-light reveals internal details.
