摘要： Additional control flexibilities to generate more gray scales for an image display system is achieved by controlling the intensity distribution of the light projection from a light source to a deflecting mirror to further coordinate with the control of the intermediate states of the deflecting mirror. The control light source intensity distribution can provide incident light with wide varieties of intensity distributions including non-uniform, symmetrical and non-symmetrical, different distributions of polarizations, various cross sectional shapes of the incident lights and other combinations of all of the above variations. More stable and better control of gray scale control is also achieved by optimizing the intensity distributions of the incident light to produce the best visual effects of the image display.
