The computer aided 3D display system, flicker-free field sequential stereoscopic image display system, is newly developed. This system is composed of personal computer, liquid crystal glasses driving card, stereoscopic display software and liquid crystal glasses. It can display field sequential stereoscopic images at refresh rate of 70 Hz to 120 Hz. A typical application of this system, 3D vision test system, is mainly discussed in this paper. This stereoscopic vision test system can test stereoscopic acuity, cross disparity, uncross disparity and dynamic stereoscopic vision quantitatively. We have taken the use of random-dot- stereograms as stereoscopic vision test charts. Through practical test experiment between Anaglyph Stereoscopic Vision Test Charts and this stereoscopic vision test system, the statistical figures and test result is given out.
