(1) A particular point, that is, a cross point of contour line along tooth tip and side edge of a tooth flank on a interference fringe pattern is needed to correspond coordinates of interference fringe pattern to ones of the tooth flank located on the measuring apparatus in case of laser interferometric measurement of a helical gear. A new corresponding method is developed in this study, and the effect of the method is experimentally investigated using a gear. Of course, this method can be adapted to non-contacting measurement of tooth flank of helical gear.(2) Because simulated images have a little deviated from contour image of interference fringe pattern in the previous study and the corresponding method of coordinates mentioned above was not sufficient, a new optical system is constructed so as to check optical precision. This enable the simulated image and contour pattern of interference fringe to correspond the both coordinates.(3) A new optical method of reducing the interference fringe, which is more simple than the previous, is proposed and the effect is experimentally investigated using a gear spur gear with large tooth depth. The availability is confirmed in the case of measurement of tooth flank form deviation for plural devided regions.

(1)激光干涉测量斜齿轮时，干涉条纹图上的干涉条纹图坐标与测量仪上的齿面坐标对应时，需要一个特定的点，即齿尖与齿面侧边轮廓线的交点。本文提出了一种新的相应方法，并以齿轮为例对该方法的效果进行了实验研究。当然，该方法也适用于斜齿轮齿面非接触式测量。(2)由于模拟图像与之前研究的干涉条纹图轮廓图像偏差较小，且上述相应的坐标方法不充分，因此构建新的光学系统来检查光学精度。这使得模拟图像和干涉条纹的轮廓图案对应于这两个坐标。(3)提出了一种比原有方法更简单的减小干涉条纹的光学方法，并采用大齿深直齿齿轮对其效果进行了实验研究。在多个划分区域的齿面形状偏差测量中，证实了该方法的有效性。
