An autostereoscopic 3D television, which displays 8 views in 1mm pitch of a lenticular sheet in 280mm × 220mm area, and whose image is seen directly on Braun tube without glasses, was demonstrated in 1987. Because the image brightness was rather low in the previous experiment, the images were observed in the dark. Recently, beam index Braun tubes having both high resolution and high brightness was newly provided. Using this tube, real-time autostereoscopic 3D TV images are now observed in ordinary circumstances. Moreover, experiments for improving the image quality are done with higher precision. In this report, important aspects of the improvements including some ideas which have been confirmed during the developments, are explained. Special emphases are on the stabilization and tracking accuracy of the index loop, and the quality of 3D images which are displayed on a cylindrically shaped composite lenticular assembly on the face plate or Braun tube.
