Lichtmikroskopie mit mechanischer Vorvergrößerung
By mechanically stretching a rubber replica prior to examination, the limits of resolution of the light microscope (according to Abbe) may be surpassed without the expenditure of any surplus energy. Replica and stretching can be described by a relief transfer function similar to that used in the optical transfer theory. This function was attained from the transfer of a step of mica. It is possible to describe the process as a linear transfer channel within the limits given.
