Abstract
We researched and demonstrated two-dimensional (2-D) deflectors constructed by on-axis type acousto-optic deflectors (AOD) in order to attain a multibeam recording for an internal drum scanning exposure system. First, we researched an on-axis AOD using anisotropic Bragg diffraction to obtain high diffraction efficiency. A significant improvement of diffraction efficiency was observed when acoustic waves are travelling in the [110] axis of paratellurite (
