Electro-optic (EO) devices are often used to capture a scene or to identify objects within a scene. Examples of electro-optic devices include still image cameras, video cameras, non-imaging tracking devices, and imaging tracking devices. These devices are capable of invading privacy and stealing information from individuals and companies. EO devices within a region are split into at least two groups, authorized and non-authorized devices.

Naval Surface Warfare Center, Crane Division (NSWC Crane), has developed and patented a method of identifying and hampering unauthorized EO devices within a scene. This technology is comprised of an optical source emitting energy into the environment towards the EO device, a detector to capture the optical energy retro-reflected from the EO device, and a controller analyzing the detected optical energy to determine whether the EO device is authorized or not. An intruder device is immobilized through a continuous beam of optical energy directed at its location.
