Latest Patents

One of Harkonen's latest patents is a method and apparatus for automatic inspection of moving surfaces. This invention utilizes at least three different illumination and observation channels. The process begins with the surface being illuminated under bright field conditions by a first beam of light from a first light source. The light reemitted from the surface is captured by a light-sensitive sensor device to obtain a first signal. Subsequently, the surface is illuminated under dark field conditions by a second and a third beam of light from additional light sources. The reemitted light from these beams is also captured to obtain second and third signals. Ultimately, a physical property of the surface is derived from the combination of these signals.
