CHOOSING PARAMETERS OF SPATIAL POSITION CONTROL OPTICAL-ELECTRONIC SYSTEMS WITH ACTIVE REFERENCE MARKS

Subject of Research.The paper considers parameters relations in active reference mark optical-electronic system of large-sized structures spatial position control in the presence of vertical temperature gradient. We describe the idea and operation principle of the dispersion method forthe vertical temperature gradient determination bycolor camera and RGB optical radiation source. The basic condition for choosing parameters of active reference mark optical-electronic system is derived from relations that define hardware realization of the system and parameters of the air tract, which are used in the dispersion method. Method. The principle of equal influence of error components on the totalerror is used. We admitted an assumption that optical radiation is propagating in the single "refractive block" and there is no fluctuations of the air tract refractive index in time and space.Main Results.The basic criterion is proposed for choosing parameters of active reference mark optical-electronic system for large-sized structuresspatial position control in thepresence of vertical temperature gradient. The efficiency of the dispersion method for minimization  of vertical temperature gradient influence is proved. The basic condition proposed gives the possibilityto estimate this efficiency and choose the hardware parameters.Practical Relevance.The results given in the paper can be used in design of active reference mark optical-electronic systems where the influence of the air tract is strong.
