METHOD OF ILLUMINATION OF OPTOELECTRONIC DEVICES FOR SMALL-SIZED UNMANNED AERIAL VEHICLES Russian patent published in 2019 - IPC F41H3/00 

FIELD: physics.

SUBSTANCE: invention relates to the field of receiving and converting laser radiation and can be used for illumination of opto-electronic devices of small-sized unmanned aerial vehicles (SUAV). For the illumination of optoelectronic devices, the radiation propagating from the SUAV, take flat-shaped detectors located on the surface of a spherical shell orthogonal to the radius vector from the center of the shell to the point of tangency with the detector. Absorbing material is placed inside the spherical shell. Determine the direction of the SUAV along the radius vector to the detector with the maximum amplitude of the recorded signal. In an automated information processing system (AIPS) calculate the power of laser radiation. According to the signals of AIPS regulate the power of the laser radiation source. Direction of radiation is regulated by a mirror installed in a magnetic field on a turntable with a conductor of electric current and a turning mechanism on the side opposite to the mirror. Conductor is in the form of ring turns located along the platform perimeter. Swivel mechanism is set in the center of gravity of the platform. Magnetic field is formed by a system of electromagnets. Electric currents of the electromagnets and ring turns are determined from the results of calculations of the AIPS from the condition of orientation of the laser radiation source in the direction normal to the surface of the detector with the maximum amplitude of the recorded signal.

EFFECT: efficiency of illumination of the SUAV opto-electronic devices is improved.
