Abstract
An optical method of measurement and an optical apparatus for determining the spatial position of at least one luminous object on a sample. A sequence of at least two compact luminous distributions of different topological families is projected onto the sample, and light re-emitted by the at least one luminous object is detected. At least one optical image is generated for each luminous distribution on the basis of the light detected. The optical images are analyzed to obtain spatiotemporal information regarding the light re-emitted by the at least one luminous object, or location of the at least one luminous object.
Claims6
A method of optical measurement for determining the spatial position of at least one luminous object in a sample, the method comprising:
- projecting onto the sample a sequence of a first compact luminous distribution and a second compact luminous distribution, wherein the first and second compact luminous distributions are of different topological families;
- formatting, in a manner selected from the group consisting of static and dynamic, the projected sequence of the first and second compact luminous distributions to provide a polarization state configured to mitigate vector effects;
- detecting light re-emitted by said at least one luminous object of the sample;
- generating from the detected light a first image of the at least one luminous object as illuminated by the first compact luminous distribution and a second image of the at least one luminous object as illuminated by the second compact luminous distribution;
- and
- algorithmically analyzing images to obtain spatial position information of said at least one luminous object.
