Abstract:
PROBLEM TO BE SOLVED: To provide a high spatial resolution inspection method using a laser scanning fluorescence microscope. SOLUTION: A sample 1 contains a substance transited repeatedly from the first state (Z1, A) to the second state (Z2, B), and the first state is different in at least one optical property from the second state. The method includes steps of: (a) transiting the substance to the first state by a switch signal 2 within a recorded sample area P; (b) inducing the second state by an optical signal 4, and for removing clearly a spatially limited partial area within the recorded sample area P; (c) reading the residual first area (Z1, A1, A2, A3) by a test signal 7; and (d) repeating the steps (a)-(c), and displacing the optical signal 4 in every repetition to scan the sample 1. The steps (a)-(d) are carried out in a sequence adapted to individual measuring situations, in the method. COPYRIGHT: (C)2007,JPO&INPIT

SOLUTION: The double confocal scanning microscope having an illumination beam path (1) of a light source (2) and a detecting beam path (3) of a detector (4) is provided with at least one optical constitution members (24 and 25) acting on the illumination beam path and/or the detecting beam path (1, 2). The optical constitution members are so constituted as to affect the amplitude and/or phase of light and/or polarized light. The microscope is thereby so constituted that the characteristics of the light are changed in the double confocal illumination beam path (1) and/or the detecting beam path (3).
