| Popis: | This note reviews the results of A. C. Hardy and applies them to the design of lens and mirror systems of recording oscillographs, such as those used in seismic prospecting. Requirements are given for maximum intensity of illumination in the recording paper consistent with small moment of inertia of the moving mirror. |
