AbstractDisplay systems play an important role in many aspects of today life including numerous scientificfields In recent decades there has been an increasing development in the technology of displayingdevices and two dimensional displaying devices are gradually replaced by their 3D counterparts Adding the third dimension to images and using other display media are two big steps to be takenin this field Therefore this thesis focuses on these two challenging problems First the methods ofcreating 3D images such as Stereoscopy Holography are studied Then various display mediaand their applications are introduced We address theoretical aspects of display devices andnonlinear optical effects of different specifically fluid media We emphasize on Acousto OpticEffect AOE due to bulk acoustic waves in transparent fluids According to AOE a noble ideawhich states that almost any kind of bulk acoustic wave patterns can be shaped in a fluid mediumwith proper stimulation of 2D continuous transducer array is introduced Also effects ofcomplexity as well as different parameters are studied for arbitrary acoustic patterns Accordingly we reach conclusions which do not suffer from limitations of classic displays and can picturenearly any kind of light dissipation by the means of some properly designed 3D acoustic pattern Finally a new method named Chain refractions method is presented for designing a suitable 3Dacoustic pattern for a predetermined light dissipation pattern At last some acoustic patterns aredesigned and modeled to produce the required angular dissipation of direct light beam in atransparent fluid medium Obviously these patterns will cause the direct beam to be seen as anilluminating dot at an arbitrary point in the fluid and therefore an image is created by putting thesedotes beside each other
