Holographic television employing acousto-optical spatial light modulator (AOM) can display a true three dimensional image that gives rise not only to binocular parallax and convergence but also the focal accommodation effects. Since the system includes mechanical scanning, it is considered as a temporary system until static display comes out. However, it is very difficult to build static system with currently available spatial light modulators. Therefore, some researches to modify AOM display are also conducted. This paper gives a review and research trends on AOM display.
