Abstract. Systems with optical equisignal zone for control over spatial location of objects are considered. It is shown that further progress in the system design may be achieved with improvement of its structure and processing algorithms. Obtained equations allow for evaluating of the optical equisignal zone base-plane displacement caused by temperature gradient, as well as the optimal time constant of the system.
Keywords: optical-electronic system, optical equisignal zone, dispersion method, optimization of components
