Patent ID: 8817089

Claim:
An inspection system for flat objects, said objects having an object surface, comprising: (a) a first holder for holding one of said objects for inspection system; (b) a second holder for holding another of said objects for inspection; (c) a first sensor assembly for receiving images or measuring values of said object surface or a portion of said object surface; (d) a second sensor assembly for receiving images or measuring values of said object surface or a portion of said object surface; (e) a driving assembly for generating a relative movement between said first holder and said first and second sensor assemblies wherein a movement is effected between said first holder relative to said first and second sensor assemblies along a first trajectory and for generating a relative movement between said second holder and said first and second sensor assemblies wherein a movement is effected between said second holder relative to said first and second sensor assemblies along a second trajectory; and wherein (f) said movement effected by said driving assembly between said first holder relative to said first and second sensor assemblies is adapted to generate relative movement of said first holder along said first trajectory between a first trajectory first position wherein images or measuring values of said object surface or a portion of said object surface of said flat object held by said first holder are received by said first sensor assembly and said first holder adjusts the object held thereby using said first sensor assembly and to a first trajectory second position wherein said first holder and said second sensor assembly are in positions wherein images of said object surface or a portion of said object surface of said flat object held by said first holder are received by said second sensor assembly, and said movement effected by said driving assembly between said second holder relative to said first and second sensor assemblies is adapted to generate relative movement of said second holder along said second trajectory between a second trajectory first position wherein images or measuring values of said object surface or a portion of said object surface of said flat object held by said second holder are received by said first sensor assembly and said second holder adjusts the object held thereby using said first sensor assembly and to a second trajectory second position wherein said second holder and said second sensor assembly are in positions wherein images of said object surface or a portion of said object surface of said flat object held by said second holder are received by said second sensor assembly, and such movement is coordinated so that when said first holder is in said first trajectory first position said second holder is in said second trajectory second position, and vice versa, in order to allow at least two objects to be treated simultaneously with said sensor assemblies.
