Abstract
The invention relates to an optical measurement method and to an optical measurement device for determining the spatial or spatiotemporal distribution of a sample, the sample comprising at least one retransmission source, said at least one retransmission source retransmitting light depending on the projected light, according to a predetermined law, onto the sample, the method comprising: the projection onto the sample of at least two compact light distributions belonging to different topological families, which propagate along the same optical path, the detection of the light retransmitted by said at least one retransmission source of the sample; the generation of at least one optical image from the detected light; and the algorithmic analysis of the optical images for obtaining location data on said at least one retransmission source.
