The purpose of this Phase I study is to determine the feasibility of a remote imaging and tracking periscope that can be free floating, but tethered to a submarine. The floating periscope contains a two- axis stabilized line of sight for various imaging visible and infrared camera systems that provide video data via a fiber-optic data link to a remote submerged submarine. The periscope to be feasible and economical uses various devices, i.e., Ir and visible cameras, stabilization systems, and trackers, and power supplied, that are already in the DOD inventory. Combining these existing devices and electronics along with an existing fiber-optic data link (army fog-m missile) into a unique periscope system and specifying the systems design requirements forms the Phase I report.
