Abstract

In Figure 1, an end view of a linear array of light shutters or valves for use as a print bar 10 in conjunction with a xerographic engine is shown. It utilizes the formation of a vapor film created by boiling a transparent liquid above an electrically heated resistive area to redirect a light beam by the means of total internal reflection. In the absence of boiling the light is transmitted with high efficiency. This is a modification of the Thermally Activated Image Bar disclosed in U.S.
