ABSTRACT:
Elongate light gate structures are composed of a plurality of individual chips of electrooptically active light gate material displaying field induced birefringence. The individual chips are provided in rectangular configuration. Each chip has a plurality of alternating electrodes and elongate light gate regions distributed there along. A rigid mounting beam has a pair of spaced parallel elongate mounting surfaces for the light gate chips and an elongate opening located between and extending along these mounting surfaces for the flow of light to or from the mounted chips. The chips may be retained on the rigid beam by chip mounting chips. The chips may be located between polarizer and analyzer filters. Driver circuit boards may be interfaced with and appropriately leveled relative to the mounted chips.
