IMAGING AND CHARACTERISATION OF THE FOCAL FIELD OF A LENS BY SPATIAL AUTOCORRELATION

摘要

Method and system, for realizing correlation, at least in space, focus light field at least two electromagnetic beams focus optical concentrating element, wherein particular spatial distribution amplitude, phase and polarization focal regions combination from focused field generate and physical responses generate focal regions placement sample focal point measurement. 1/ or multidimensional spatial displacement focus areas peat push away a focus areas at least two beams introduce relative to other at least two wave beams. The relative phase of beam by (periodicity) variable optical path length at least one light beam. Physical responses, due to physical process sample as consequence scattering focal regions sample, and detect, the physical responses for the specific space-time yield distribution being combined optionally with the aid of specific collection function are in the concentrating element. Possible physical responses sample is subjected to above-mentioned field of focus and is measured by the following method through collection function when microscope imaging has increased laterally and/or axially resolution ratio, it can with or be not necessarily specific. In addition, quantitative structure on room and time, is related to a propagation function, focusing on light field concentrating element and by its optical axis can be determined, according to amplitude, phase or polarization.
