    • A three-dimensional shape measuring apparatus which has an improved arrayed confocal imaging system. A three-dimensional shape measuring apparatus using a confocal imaging system which has a new means for changing the distance in the Z direction between the object and the object-position-in-focus, instead of an object stage moved in the Z direction. This means shifts the object-position-in-focus in the Z direction by refraction. One means inserts a plurality of transparent flat plates between the objective lens and the object-position-in-focus in turn. Another means uses a transparent flat plate made of a material for which the refractive index changes according to the voltage applied and is disposed between the object and the object-position-in-focus. A three-dimensional shape measuring apparatus using a confocal imaging system wherein an image processor estimates the position from which the intensity of the reflected light for each pixel of the confocal image becomes maximum by interpolation of a value from the curve of the relationship between the intensity of light detected and the distance from the object-position-in-focus to an object point.

    • The micro-scanning multislit confocal image acquisition apparatus of the present invention is a confocal image acquisition apparatus that comprises a nonscanning multislit confocal image acquisition system using a slit array instead of a pinhole array and a multislit-image microscanning mechanism for moving the image of the slit array in a small back and forth motion with respect to the object during each exposure of the two-dimensional arrayed photodetector in one complete measurement. Microscanning the image of the slit array with an amplitude equal to half the distance between adjacent slits increase the aperture ratio of the pixels to 100 percent, reducing blind regions to zero. As a result, this apparatus can measure a small object that cannot be measured by a conventional nonscanning confocal image acquisition apparatus because of blind regions. Microscanning the image of the slit array can also reduce the effect of speckles, another problem of a conventional nonscanning confocal image acquisition apparatus, by averaging the reflected light passing through each aperture of the slit array.
    • 本发明的微扫描多照相共焦图像获取装置是一种共焦图像获取装置,其包括使用狭缝阵列而不是针孔阵列的非渐变多照明共焦图像采集系统和用于移动图像的多照片图像显微机构 狭缝阵列在一次完全测量中在二维阵列式光电检测器的每次曝光期间相对于物体的小的前后运动。 以等于相邻狭缝之间的距离的一半的幅度扫描狭缝阵列的图像将像素的孔径比增加到100%,将盲区减少到零。 结果,该装置可以测量由于盲区而不能由传统的非相干共聚焦图像获取装置测量的小物体。 通过对穿过狭缝阵列的每个孔的反射光进行平均,微扫扫缝阵列的图像也可以减少斑点的影响,这是传统非相干共聚焦图像获取装置的另一个问题。
