摘　　要：定量分析了平行光入射空气劈尖和介质劈尖时,干涉条纹严格定域在劈尖上界面处时的条纹间距.数值计算表明对两种劈尖作光线垂直入射垂直反射的近似处理时,空气劈尖的误差较大,但是小于4%.The distance for two adjacent interference fringes in wedge stricken by parallel light is quantitatively analyzed for two kinds of wedges without the approximate treatment,in which the vertical light is reflected vertically.Numerical computation indicates the error for an air wedge is bigger than that for a glass wedge,but the error is still smaller than 4%.

关 键 词：劈尖干涉 误差 条纹
