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.

The diameter of a wheel or wheels, such as railroad wheels, is measured while the wheel rolls through a measuring station or while a measuring station is moved past a wheel. Electromagnetic beams, such as light or laser beams, provide respective barriers or sensors. The spacing between the beams is fixed and the time needed to traverse the spacing is measured. The spacing has a definite relationship to the wheel diameter. A computer calculates the diameter based on the measured time and on the given wheel diameter related spacing. Even where only a portion of a wheel is available for sensing or scanning the present method may be used.

A method and apparatus for detecting leakage in a shielded, radioactive hot ell having drip leakage-endangered sections, including a light source and polarizing element for irradiating the leakage-endangered sections with light, reflecting the light to a polarized photosensitive receiver, and an apparatus for comparing the received and reflected light with a threshhold value and for sounding an alarm whenever the comparison exceed predetermined limits. The method constitutes the steps for practicing the operation of the apparatus.
