| description | A method for testing components of transparent material for surface irregularities and occlusions, comprising the steps of dot-scanning the component by moving a light ray completely therethrough; detecting the light which represents flaws in at least the front and back surfaces of the component by receivers located on one side of the component; generating fault signals based on the light detected in the detecting step; digitizing the fault signals which are generated in the generating step; feeding the digitized signal to a mapped memory; and analyzing the signal by: (a) feeding the digitized signal to a number of sector counters via a preselectable number of thresholds; (b) evaluating the sector counters on-line according to preselected criterion regarding the number, location and gray tone distribution of the digitized fault signals; and (c) evaluating the signals in the mapped memory in a computer if the fulfillment of the criterion for evaluation of the sector counters cannot be sufficiently assured. |
