Abstract
Generally non-glass type three dimensional stereoscopic display systems should be considering human factor. Human factor include the crosstalk, motion parallax, types of display, lighting, age, unknown aspects around the human factors issues and user experience. Among these human factors, the crosstalk is very important human factor because; it reduces 3D effect and induces eye fatigue or dizziness. In these reason, we considered method of reduction crosstalk in three dimensional stereoscopic display systems. In this paper, we suggest method of reduction crosstalk using lenticular lens. Optical ray derived from projection optical system, converted to viewing zone shape by convolution of two apertures. In this condition, we can minimize and control the beam width by optical properties of lenticular lens (refractive, pitch, thickness, radius of curvature) and optical properties of projector (projection distance, optical features). In this processing, Gaussian distribution type shape is converted to rectangular distribution type shape. According to the beam width reduction will be reduce crosstalk, and it was verified used to lenticular lens.
