Abstract
We have studied flare effects induced in liquid crystal filters for video image capturing. The relationship between the concentration of spacer particles dispersed in the liquid crystal device and the intensity of light scattered by the device was examined in detail using a Schlieren optical system. The scattered light intensity was decreased with proportion to the spacer concentration. It was also found that the alignment disorder of liquid crystal molecules around the spacers causes considerable light scattering. The flare effect appeared in video images was reduced according to the decrease of light scattering.
