Abstract
Subject of the research. Parameters relations in active reference mark optical-electronic system spatial position control in presence of vertical temperature gradient is considered. The operation principle of the dispersion method of the vertical temperature gradient determination using colour camera and RGB optical radiation source is described. 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 total error is used. There is an assumption that there are no fluctuations of the air tract refractive index in time and space. Main results. The basic condition for choosing parameters of active reference mark optical-electronic system for spatial position control in presence of vertical temperature gradient is proposed. The efficiency of the dispersion method vertical temperature gradient influence minimization is proved. The basic condition proposed condition allows to estimate this efficiency and choose the hardware parameters. Practical significance. 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.
