| 抄録 | A method of generating an unusual light beam, long range nondiffracting beam (LRNB) has been studied. The LRNB propagates over a long range keeping its narrow beam width as if it does not diffract, while general light beams spread by the diffraction effect. The new beam can be generated by a technique of wave front control, e.g., by a distorted concave spherical wave front that can be formed by a Galilean transmitting telescope with an eye-piece that has a spherical aberration. There will be introduced some results of experiments as well as theoretical analyses of the LRNB generation using a unique optical system with a telescope and a laser. |
