Non-Intrusive Missile Control Surface Monitor System

摘要

The non-intrusive missile control surface monitor system uses opticaltechnologies for nonintrusive monitoring of various aspects of the movements of a missile control surface (or any control surface) that is undergoing electromagnetic testing. The system comprises a laser source, an optical detector positioned opposite the laser source, an attenuator assembly, which is a framed translucent grey-scale shaded window positioned between the laser source and the detector, and means for recording output signals derived from the detector. The attenuator assembly is an electromagnetically transparent member, mounted on the missile control surface. The attenuator assembly moves in concert with the missile control surface and yet does not affect the electromagnetic signature of the missile. Generated laser beams project on the grey-scale shaded window. The grey-scale shading affects the intensity of the directed laser beams (the darker areas attenuate more light and the lighter areas allow more light to pass through). Accordingly, data are obtained by optical detecting of the different light intensities passing through the translucent grey-scale shaded window, which are directly related in synchronization with the movements of the attenuator assembly and, therefore, the missile control surface.
