PHOTOCONDUCTOR DEVICE FOR IMAGING A LINEAR OBJECT

PHOTOCONDUCTOR DEVICE FOR IMAGING A LINEAR OBJECT A photoconductive device for imaging a linear object has a plurality of photoconductive elements, extending in a line, on a substrate, with first and second patterns of electrical conductors, a pattern on each side of the line. Connections are made to the elements. The conductor patterns are formed as columns on one side of the line and as rows on the other side to provide connections between columns and elements and rows and elements such that the number of external connections is minimized. By applying a voltage to a column, and then connecting a detector circuit sequentially to each row, and repeating for each column, the current flowing through each element can be determined and a signal generated related to the illumination of each element. The elements can be a continuous bar of photoconductive material.
