Abstract
In order to realize autostereoscopic 3D projecting display with higher brightness and larger size, a technique of autostereoscopic 3D projecting using parallax barriers and lenticular sheets is proposed.The parameter design of lenticular sheets and parallax barriers is investigated. First, projection distance of projector array is confirmed according to eye's resolution,then the strips' character of lenticular sheets is analysed by zemax in four-view situation,thickness and parameters of strips of lenticular sheets are confirmed. Finally, the width of slit and pitch and viewing distance and etc of parallax barriers are confirmed according to parameters of strips of lenticular sheets. Data analysis indicate that the brightness of our four-view image is increased three times because of using lenticular sheets instead of parallax barriers comparing with the autostereoscopic 3D projector using two parallax barriers plates. Parameters design of parallax barriers and lenticular sheets are finished, the feasibility and advantages of the 3D display of projecting are confirmed theoretically.
