LASER BEACON FOR VIRTUAL REALITY SYSTEMS WITH 360 DEGREE SCANNING OF ENVIRONMENT Russian patent published in 2023 - IPC G01S1/70 

FIELD: tracking location of objects.

SUBSTANCE: laser beacon for virtual reality systems with 360-degree scanning of the surrounding space consists of a chassis; mounted on the body of the engine with a hollow rotor, with the help of which a rotating hollow drum in the form of a truncated cone with an angle at the top of the cone 2β, equal to: β = 90° - arctg(tg(α₀/2)cos(γ)),where α₀ is the full opening angle of the fan-shaped plane, γ is the angle of inclination of the plane of the fan-shaped laser beam to the plane of rotation; two lenticulars mounted on the side wall of the drum, with the help of which laser fan-shaped beams are formed, the planes of which are oriented at different angles to the plane of rotation ±γ; reflecting isosceles prism, which is rigidly mounted on the drum symmetrically to the axis of rotation, while the axis of rotation of the rotor passes through the top of the prism, and the angle at the top of the prism is equal to: θ = 90 - β a laser the radiation of which passes through a collimator; a block for modulating laser radiation and encoding an omnidirectional synchronization pulse; a block for generating an omnidirectional synchronization pulse; rotor speed sensor to determine the moment of emission of an omnidirectional synchronization pulse at the beginning of each scan cycle.

EFFECT: provision of 360° space scanning with the possibility of mounting the device on the ceiling and on any surface inaccessible to the operator.
