Abstract. Error of object location by optical-electronic position-control system with polychromatic equisignal zone with the use of the dispersion method is considered. A component of the error which may not be eliminated is found. The component is shown to depend on the system optical parameters, distance to the object under control, and the used wavelengths. Results of numerical simulation reveal a possibility to reduce the error component by optimization of the optical system parameters.
