A METHOD OF OBTAINING A UNIFORM BEAM OF ELECTROMAGNETIC RADIATION OF ARBITRARY GEOMETRICAL SHAPE AND A MECHANICAL-OPTICAL DEVICE FOR APPLICATION OF THIS METHOD

摘要

The method of obtaining a uniform beam of electromagnetic radiation with arbitrary geometrical shape by means of lens optical system consists in that a source of artificial light (2) emitting light is connected to the electric power network and electromagnetic light rays (20) are emitted by the source; then, depending on the required light projection shape (23-27) and (34-36), a uniform beam of electromagnetic radiation is directed onto appropriate input lens (3), preferably a cylindrical plano-convex lens with fixed or adjustable focal length "A"', and the light rays (21) coming out of the lens are directed onto an output set of lenses or an output panel set of lenses (4) with fixed or adjustable position with respect to the input lens (3), i.e. inclined at angle "a" ranging from 0° to 75°, and after passing through the lens or the panel set of lenses (4), the rays are directed onto the desired plane forming the required shape of light projection (23-27) and (34-36) with sharply outlined side edges.
