METHOD FOR LASER SCANNING OF FLUIDS IN HOLLOW PRISMS Russian patent published in 2025 - IPC G01N21/29 

FIELD: optics.

SUBSTANCE: invention relates to optical methods of analysis, to a method for laser scanning of fluids in hollow prisms. Method for laser scanning of liquids in hollow prisms includes formation of laser beams by means of separate laser modules with wavelengths of 405, 450, 488, 532, 589, 635 and 685 nm, which through the system of light filters are combined into one dense parallel beam, which, when passing through a hollow transparent prism filled with the analysed material, is refracted in accordance with the optical density of the material in the prism, wherein the nature of refraction of each of the laser beams passing through the prism with the analysed material is fixed on the screen and transmitted to the computer display, where it is compared with the nature of refraction of the same laser beams, which have passed and refracted through control materials, wherein one of the faces of the hollow prism is made from material with a high refraction index, in the form of a monolithic prism, and is located along the normal to the incoming beam of laser beams.

EFFECT: possibility of analysing materials with a high refraction index and with a low refraction index close to one.
