1. A system that structures emitted light to be undetectable to certain types of external light detection systems, said system comprising a light emitting device, wherein the system:
causes the light emitting device to emit light into an environment, wherein the light emitting device causes the emitted light to have a predetermined roll off rate;
causes the light emitting device to set an intensity of the emitted light to a level that results in the emitted light being undetectable to said certain types of external light detection systems when those certain types of external light detection systems are at least a known distance away from the light emitting device, the known distance being computed based on the roll off rate; and
triggers generation of an image of the environment while the light emitting device is emitting the light into the environment.
