Claim 14:
15. An optical measuring device for determining information selected from the group consisting of a spatial distribution and a location of a set of re-emitting sources on a sample, the sample comprising at least one re-emitting source, excited by light projected on the sample and re-emitting light according to a law determined as a function of the projected light, the device comprising:
a projection module containing a laser, whereof the wavelength is aligned to an excitation wavelength of said set of re-emitting sources to create a sequence of the compact light distributions of different topology,
a detection module for detecting the light re-emitted by said set of re-emitting sources on the sample for the or for each of the compact light distributions of different topology and for each of the scanning points of the sample;
an image acquisition module for acquiring, from the detected re-emitted light, for each scanning point a set of images, the set having at least one member, each image corresponding to one of the compact light distributions of different topologies;
an algorithm module configured to reconstruct properties of the sample from the set of images, the properties selected from the group consisting of the sample itself, its spatial properties, its temporal properties, its spectral properties, and combinations thereof, based on a reverse Bayesian problem leading to definition of a distribution a posteriori by way of Bayes law, and a posteriori combining the probabilistic formulation of a noise model, as well as any a priori on a light distribution created in the sample by projection,
a MAP algorithm module configured to apply a MAP algorithm; and
a representation module configured to represent results, based on the MAP algorithm, in a form selected from the group consisting of an image, digital data, graphic data, and combinations thereof.
