An electro-optic tunablerectangulararrayilluminator in one-dimensional periodicallypoledlinbo3 (PPLN) crystal is presented experimentally which result is in good agreement with results from simu- lation. The illuminator is formed based on the Talbot self-imaging effect by applying an electric field on PPLN. The intensi~.y distribution of rectangulararray could be precisely modulated. Compared with other arrayilluminators, this tunableilluminator uses a lower voltage and could get a more concentrated intensity distribution. The influence of the incident angle to the self-imaging patterns is studied for the first time.
