POINTWISE SCANNING OF AN INFORMATION SURFACE |
摘要 |
An apparatus is described for the pointwise scanning of an information surface. By arranging an observation objective system asymmetrically relative to a zero-order subbeam of the radiation coming from the information surface, and by utilizing a detector whose dimension in the scanning direction is small, the resolution can be increased. |
