Paper Abstract

It is possible to extract the contour of images without such effects as shading, by adding a circular deflec tion as sub-deflection to the image camera tube and then by extracting from them AC-portion alone. Further, it is possible to seek the mark's gradient as well as the relative deviation of the mark from sub-deflection, by effecting synchronized rectification for these video signals by means of the sub-deflecting carrier and the other carrier having a frequency twice the sub-deflecting one. The prototype model of the Mark-Position Measuring Device is realized by analogue technique, using an Image Dissector Camera.
