Abstract

In this paper, we present a novel display assembly which is specially designed for the immersive system to enhance the sense of immerse. In particular, we aim at improving the display when a bright object, such as a light source, appears in the field of view. In the proposed assembly, we adopt a spot light to generate a high intensity beam. When the beam hits the screen, a hot spot is formed to imitate the light source displayed on screen. A galvanometer is employed to deflect the beam so we can track the moving of the light source displayed. Based on the basic laws in photometry, we deduct a series of formulas which could calculate the intensity of the beam and to estimate the gain in the contrast and dynamic range.
