Method and device for superresolution optical measurement using singular optics

A method of optical measurement for determining the spatial position of at least one luminous object in a sample, the method comprising:

• a. creating a set of light distributions in parallel;
• b. modifying each one of the light distributions in the set of parallel light distributions, using an optical module, to create a first set of compact luminous distributions;
• c. projecting the first set of compact luminous distributions onto the sample in parallel, onto a plurality of discrete points on the sample;
• d. modifying the parallel light distributions, using the optical module to create a second set of compact luminous distributions;
• e. projecting, the second set of luminous distributions, in parallel, onto the sample on the same points on the sample as those illuminated by the first set of compact luminous distributions;
• wherein the first and second compact luminous distributions are of different topological families;
• f. detecting light re-emitted by the at least one luminous object and generating from the detected light a first image of the at least one luminous object as illuminated by the first set of compact luminous distributions and a second image of the at least one luminous object as illuminated by the second set of compact luminous distributions;
• and
• g. algorithmically analyzing the first and second images to obtain spatial position information of the at least one luminous object.
