METHOD AND DEVICE FOR OPTOELECTRONIC ALL-ROUND VIEW Russian patent published in 2011 - IPC G01S3/78 

FIELD: physics.

SUBSTANCE: in the method for optoelectronic all-round view, involving reception of infrared and optical radiation with possibility of rotation in the azimuthal plane by a multi-phase angle of rotation, generation of a signal for presence of radiation and direction thereof in the azimuthal plane, optical radiation of the image is recorded through video capturing synchronously with reception of infrared radiation on video capturing object by scanning in the azimuthal plane the corresponding phase rotation angle with clock pulses at fixed frequency. The phase rotation angle scanning is converted to a code proportional to clock pulses from the beginning of recording bi-directional phase increment until zeroing thereof owing to measurement of the code N_j with successive approximation with a standard value N_0j on the condition that: if the measured code N_j is greater than the standardised N_0j, the latter is increased by summation of pulses, otherwise through subtraction thereof, if N_j =N_0j the number of pulses does not change and the standardised code is taken as the measured code. In the all-round vie optoelectronic device, having units for receiving infrared and optical radiation with possibility of rotation in the azimuthal plane by a drive with a phase rotation angle sensor in form of a sector-annular multi-phase structure and a generator for generating the radiation presence signal and direction thereof in the azimuthal plane. The optical radiation receiver is a video camera fitted in the scanner the infrared radiation receiving unit, which manages rotation in the azimuthal plane by a drive with an infrared sensor of the phase rotation angle, lying coaxially between movable and fixed sector-annular structures of the scanner. The infrared radiation receiver is a photodiode matrix which is connected on a multi-phase bridge switch scheme consisting of a parallel connection of two voltage dividers, made through serial connection of a resistor and phase photodiodes of the matrix, wherein the input diagonal of the multi-phase bridge switch serves for connecting an energy source, and its output diagonal is loaded by an actuating mechanism of the drive of the device scanner, the generator for generating the radiation presence signal and direction thereof in the azimuthal plane is made on an infrared light-emitting diode with a standalone power source in decorative form, for example an icon on the captured object.

EFFECT: high metrological efficiency owing to automation of panoramic video surveillance with controlled accuracy of the standardised measure of the phase of the rotation angle in the azimuthal plane.
