Optical marking of radiation beam

摘要

A system for optical marking of electromagnetic radiation has a source of collimated radiation, like a laser diode or luminescent diode, and a diffractive optical system as a point of impact for this radiation. From the optical system, the radiation is transmitted so that it spreads out partly or fully over a conical or pyramidal surface. There is a deflection system following the optical system to mark the edges of the emitted and received primary radiation bundle. Part of the radiation emerges undeflected from the second system and is used to mark the middle of the radiation bundle. The deflection system contains prisms and mirrors.
