Abstract:
A shadow band assembly includes a platform and an arcuate shadow arm extending upward from the platform and terminating in a free end above the platform. A sun sensor mounting location is located below the free end of the shadow arm. The arm is preferably further supported by a vertical strut. According to other embodiments, the arm is hollow and contains a fluid conduit and/or an electrical cable. A sun sensor may be mounted on top of the free end of the arm and a fluid nozzle may be mounted under the free end. A shadow band pyranometer includes the shadow band assembly, a sun sensor mounted at the mounting location and a motor drive coupled to the platform for azimuth tracking. Additional sensors with zenith tracking may also be provided.
Abstract:
A packaged optical device includes a package frame having a compartment and an opening, a sensor chip bonded in the compartment, and a non-lens transparency layer embedded in the package frame at the opening and sealing up the opening. This package structure could prevent the sensor chip from adhesion of suspended particles or other contaminations, and simply the assembly process, thereby improving reliability and reducing cost of the packaged optical device.
Abstract:
This invention advances the related state-of-the-art by eliminating the physical EO window used by electro-optical imaging infrared seekers for tactical missiles and high-altitude endo-atmospheric interceptors, widely employed in integrated defense systems. This invention increases the probability of intercepting exo-atmospheric ballistic warheads by exo-atmospheric interceptors, and eliminates the existing altitude “gap” of interception, as well as the geographical limitations posed by the mesospheric Noctilucent Clouds. The problem of protecting an imaging EO sensor from aeroheating is solved in this invention by a special purpose device which is enabled immediately after the nose cone ejection event. The role of said device is to augment the sensor fixed sunshade and cavity lengths in the forward direction, and by doing so, the resulting new cavity enables the optimal injection of an optically inert gas into the new extended cavity in front of the sensor, thus effectively blocking the entry of the compressed hot air into the sensor cavity, while simultaneously avoiding any adverse effects of inducing flow instabilities in the flow as well as the disturbance of the injected gas flow on sensor structures. Having a greater length for the hot gas to penetrate, eliminates also the penetration of suspended particles in oncoming air stream.
