FIELD: measuring equipment.
SUBSTANCE: invention relates to instrument-making, mainly to measurement equipment. To achieve technical result, Hanbury-Brown-Twiss interferometer is added to atomic-power microscope with cantilever with fluorescent quantum point, having beam-splitting device, dividing light beam in equal proportions (50:50), a second photodetector for detecting fluorescent radiation, as well as a device for calculating a cross-correlation function.
EFFECT: possibility of measuring anti-grouping of photons in an APM using cantilevers with fluorescent quantum points on the tip of a cantilever probe.
