摘要
本研究根据云纹产生的原理,试制了SCC—I型头部云纹摄影仪。此仪器设计及制作简便,易于操作,易于推广。经检定此仪器最大误差不超过0.12mm,可重复性达95.7％以上,能够满足面部畸形整复的需要。摄影时头颅可以分别处于0°:30°及45°三种位置上,分别获得正位云纹片、侧位30°及45°云纹片,从而三维地记录及测量面部形态,云纹片具有可比性。
According to the principle of Moire, Moire cephalometric apparatus (model SCC-I) was made, with the features of simple design and easy popularization. In the light of testing. It turns out according to our test that our apparatus with less error (<0.l2mm ) and high repeat (>95.7%) can meet the needs of the reconstruction of facial deformities. Because the head can be photograph in 0°, 30° and 45°respectively, from which the Moire pholographes of frontal and lateral 30°and 45°can be obtained, the facial shape can be record and measured in the three dimension, with constant Moire photographic
