Abstract
A method and apparatus is disclosed for the automatic and rapid recognition of faults in a surface or dimensions of an object, or for recognizing a position of the object in a field of view of an observation and/or measuring device. A photodiode row is provided having an active surface with a length dimension substantially greater than its width dimension. An anamorphotic lens system is provided which focuses a first dimension of the field of view onto the active surface length dimension and which focuses a second orthogonal dimension of the field of view onto the active surface width dimension. By means of signals from the photodiode row, theoretical dimensions can be compared with actual measured dimensions of the object.
