摘要： A 6 degree-of-freedom (DOF) motion measuring apparatus using a multidirectional reflector, and a swing arm type optical system using the 6-DOF motion measuring apparatus to measure the 6-DOF motion of a slider in a hard disc drive (HDD) are provided. The 6-DOF motion measuring apparatus includes: a multidirectional reflector having at least three reflecting sides by which the laser beam is slit and reflected in three directions, the multidirectional reflector being provided to the object whose motion is to be measured; three position-sensitive detectors for receiving three sub-laser beams reflected from the multidirectional reflector; and a controller for calculating the 6-DOF motion of the multidirectional reflector using the intensity distributions of the three sub-laser beams received by the three position sensitive detectors assuming that the laser beam before reflection has a Gaussian intensity distribution. The 6-DOF motion of an object can be easily and precisely measured using the multidirectional reflector having three reflecting sides. The 6-DOF motion measuring apparatus can be applied to measure the displacement of a small object moving at high speed.

摘要： A laminography system includes a table, an X-ray source, an image intensifier, a view selector and a camera. The view selector has a prism for refracting a ray of light, and an adjusting part for adjusting the prism to a position in which images at a certain area of an image projecting plane of the image intensifier are received into the camera. The adjusting part has a first motor for rotating the prism along the circumferential direction of the image intensifier, and a second motor for rotating the prism in a direction perpendicular with respect to a radial direction of the image intensifier. Accordingly, the images at any areas of the image projecting plane of the image intensifier can be obtained. In addition, since an optical axis of the image passing through the prism and then received into the camera is in perpendicular relation with the camera, no image distortions occur.
