Subject of Research. The paper considers the alternate design of nondestructive jamming in the visible light range. Two different approaches utilizing coherent and incoherent light emitters are approved to suppress visual-optical and electro-optical channels of equipment surveillance. Method. The design relations are examined and graphically illustrated. The numerical calculation of irradiance from energetically equivalent coherent and incoherent narrow beam emitters is performed in the range of exposure distances equal to 100–2000 m while changing radiated power and beam width. Main Results. The quantitative parameters are obtained for irradiance generation above the criterion levels of function destruction, suppression, and negation of applying optical devices. We analyze the usage of optical means for emitters with commercially available compact diode-pumped solid-state visible beam lasers and for emitters utilizing high intensity miniature cermet case short-arc xenon lamps with fixed integrated reflector enhanced with secondary forming optical system. The correlation between the criterion levels and the range of exposure distances is identified. The variation limits of the radiated power and the beam width are established at close distances to satisfy the condition of nondestructive effects. Practical Relevance. Comparative study results and the design relations might be useful for development of nondestructive visual-optical jammers utilizing coherent and incoherent emitters and for determination of function degradation criterion levels for multi-level exposure.
