A 3 dimensional image sensor is developed with only a CCD camera and with rotating mirrors as a periscope. Many images are captured at every a few degrees of periscope rotation. The distance, along optical axis of camera, from the focal point of camera system to a certain point at object surface is inversely proportional to the parallax. In this system, a circler streak is obtained by tracing a point on each image by using the cross-correlation along a direction of periscope shift. The parallax can be calculated from the radius of streak. This method is robust against the texture-less images and against the variation of brightness in the images. Applying this method to shape measurement of human face, it is well reconstructed and this system may have a possibility to adapt for a simple handy 3D-scanner.
