Patent ID: 8358829

Claim:
An inspection system, comprising: a first group of sensors, for sensing light components of a first light band of an image of an area of an inspected object, and for generating first detection signals reflecting sensed light components of the first light band; a second group of sensors, for sensing light components of a second light band of the image of the area of the inspected object, and for generating second detection signals reflecting sensed light components of the second light band, wherein the second light band differs from the first light band, wherein the second group of sensors is arranged to sense the light components of the second light band while the first group of sensors senses the light components of the first light band; optics, for projecting the image of the area of the inspected object towards the first group of sensors and towards the second array of sensors; and a processing unit, coupled to the first and second group of sensors, for detecting a first type of defects based on the first detection signals and for detecting a second type of defects based on the second detection signals.
