摘要
目的：研制一种新型的立体视觉检查图卡及相应观片装置。方法：立体视觉检查图卡含随机点图对合成、普通图对合成、彩色体视图对合成以及非图对合成４ 种，采用彩虹全息技术制作。观片装置有眼位固定标志、特定角度照明、选择使用的点光源及带状光源。结果和结论：依据该设计制作的样机显示，裸眼即可进行立体视锐度检查，且因能防止强记猜图，检查条件规范，检查结果的可靠性明显提高。
Objective: To develop a new type of stereopsis test charts and relevant graph viewing device. Methods: The charts, containing random dot pair synthesized,line drawing pair synthesized,color photograph pair synthesized and non synthesized stereograms, were made with rainbow holography. The device has an eye position indicator symbol and two kinds of light illuminating the chart from the given orientation. Results and Conclusion: Using the prototype of the apparatus based on this design, the stereoptic vision test can be carried out with naked eyes, and the test result is reliable due to the prevention of guess at the graph and the guarantee of the stipulated test condition.
