采用漫反射的方法,在安静和噪声2种不同环境下,考虑物光与参考光之间夹角、曝光时间、显影时间等各种不同情况对规则和不规则的2种物体分别进行拍照,得到全息摄影技术的最佳实验条件,即物光与参考光夹角介于30°～50°;曝光时间在10～20 s;显影时间在30 s之内,要视显影液配置的时间长短,最好不要超过1 min.不规则物体拍摄时,物体与全息底片之间的距离越近越好,一般在2～3 cm;规则物体与底片间距离可在8～10 cm.该实验为全息光栅的制作、全息干涉测量等实验提供较有力的实验支持.

Taking holographs of regular and irregular objects with diffuse reflection method in quiet and noisy conditions by considering the angler of object and reference optics,exposal time,developing time and other factors,and the best experimental conditions is found that the angler of object and reference optics is 30°—50°,exposal time is 10—20 s,the best developing time is in 30 s and not more than one minute to be meet the time of photographic developer.If the object is irregular,the nearer of the distance between object and negative,the better of the effect,normally it is in 2—3 cm.If the object is regular,the distance between object and negative could be in 8—10 cm.The results afford experimental support for the experiments of holographic grating,holographic interference measure and so on.
