【摘要】 目的为探讨在飞行人员选拔时采用立体视觉检查的必要性及用白噪声图检查立体视觉的飞行人员选拔标准。方法用该仪器对457名现役飞行员进行了检查，并以275名视力正常现役地勤人员作为对照。另对在飞和因技术停飞的学员各30名的立体视觉作了对比。结果飞行人员立体视觉明显优于地勤人员，在飞组学员优于停飞组学员。457名飞行员按年龄分组的检查结果，在45岁前，年龄与立体视觉无关。结论在飞行员选拔中有必要检查立体视觉；空、地勤人员立体视觉不宜采用同一标准。建议用本仪器选拔飞行人员的标准为立体视敏锐度≤30″角，交叉和非交叉视差各为200’角。更多还原

【Abstract】 Objective To investigate the necessity of employing stereopic examination in selection of flying cadets, and set a criterion for it. Methods The stereoscopic acuity(SA) was examined in457 pilots on active duty by white noise stereogram taking 275 groundcrew with normal visual acuity ascontrol. In addition, a contrast survey of stereopic acuity was done between 30 student pilots groundeddue to poor performance and 30 student pilots in service. Results The results showed that the SA inpilots was significantly higher than that in groundcrew,and SA of student pilots in service was betterthan that of grounded. The differences among SA of different age groups of pilots were nonsignificant.Conclusion It is concluded that, stereoscopic examination is necessary for selection of flying cadetsUsing white noise stereogram,the suggested criterion is stereoscopic oxyopy ≤30",crossed parallax andnoncrossed parallax 200’.更多还原
