| Popis: | 99 In this paper, we proposed a technique to realize the three-dimensional (3D) telescope based on the critical angle method and the use of a CCD camera. A general optical telescope is just only used to observe two-dimensional image of a far object. Because the intensity ratio is proportional to the depth of the object in the internal reflection method, we used a commercial telescope combined with a parallelogram prism and a CCD to achieve a pattern which is the intensity ratio of images caught by the CCD at two incident angles of the prism, and then the object depth can be obtained. Therefore, the 3D topography is also obtained. The 3D telescope is very compact and useful in sufficient light condition. None of light sources is necessary unless the object is under the status of unsufficient illuminance. Therefore, it is more convenient for users to apply the technique in remote measurements. |
