FIELD: optical instrumentation.
SUBSTANCE: invention concerns a method for forming a photonic jet. The method involves placing one or more microlenses made in the form of spherical meso-sized particles on the shadow surface of a flat transparent substrate, and irradiating with electromagnetic radiation with a formed flat wave front of the substrate surface opposite the shadow surface. The substrate consists of two layers with a common boundary in the same plane of materials with different refractive indices, less than the refractive index of the material of the mesosized particle, and the spherical particle is placed on the substrate so as to always be on two layers of material.
EFFECT: improving the quality and increasing the contrast of the resulting image.
