A DEVICE FOR DETERMINING THE COLOR OF A TARGET ELEMENT IN A CONTROLLED AREA Russian patent published in 2022 - IPC F41G7/26 G06F3/14 

FIELD: optical instrument engineering.

SUBSTANCE: invention relates to the optical instrument engineering and can be used for the development of multi-channel survey and search systems that detect a target in a controlled area, highlight it on various backgrounds, determine its coordinates and the color of its elements. A DC power supply, the first and second converters, a subtraction unit, a source of electromagnetic oscillations with varactor frequency tuning, a graduated unit for measuring the target image are introduced into a device for determining the color of a target element in a controlled area containing a multi-channel guidance system using a reference image and determining the recognition of the target image by ensuring the independence of the standard from the conditions of its observation. the color indicator, made in the form of an electronic analog device with a scale and division of the correspondence of wavelength and color, an indicator and a feedback unit with the ability to regulate the supply voltage at the input of the varactor of the electromagnetic oscillation source, and the output of the multichannel guidance system is connected to the input of the first converter, the output of the latter is connected to the first input of the subtraction unit, the output of the subtraction unit is connected with the inputs of the indicator and the feedback unit, the output of the feedback unit is connected to the power input of the varactor of the electromagnetic oscillation source, the power input of which is connected to a DC power source, the output of the energy of the electromagnetic oscillation source is connected to the input of the second converter, the output of the latter is connected to the second input of the subtraction unit and the input of the color graded block.

EFFECT: present invention enables to expand the functionality of determining the color of the target element in the controlled area.
