摘要:
Subwave length‐resolution optical image recording is demonstrated by moving an extremely narrow aperture along a test object equipped with fine‐line structures. Details of 25‐nm size can be recognized using 488‐nm radiation. The result indicates a resolving power of at least &lgr;/20 which is to be compared with the values of &lgr;/2.3 obtainable in conventional optical microscopy.
