Active and passive techniques to cloak a target will ultimately determine its ability to survive by avoiding detection and tracking. Holographic technology has the unique compatibility of being able to deflectincoming radiation in a pattern that is determined when the holographic film is made. Thus, the possibility of having the beam from a laser rangefinder, for example, completely misdirected away from an aircraft (missile) in a direction that is advantageous for avoiding detection is currently within the state of the art. Holographic technology hasthe ability to reject very narrow wavelength bands (delta lambda = 20nm) or very broad bands (delta lambda = 400nm) of the visible and infrared spectral regions. Holographic mirrors can be tuned to reflect specific laser wavelengths with reflectivities of 99.9% (experimentally measured). It can do this with high optical density (od >6). Applications of cloaking to military devices and sensors from tactical lasersappears straightforward.
