Self-Nulling Beam Combiner Using No External Phase Inverter
A self-nulling beam combiner is proposed that completely eliminates the phase inversion subsystem from the nulling interferometer, and instead uses the intrinsic phase shifts in the beam splitters. Simplifying the flight instrument in this way will be a valuable enhancement of mission...

Volume-Changing Primary Glass Material
This technology produces a silica glass material with a promising negative refractive index. The material changes volume via irradiation under UV light, and results in a refractive index capability of 10-2. This makes it applicable to a wide range of fields, including holograms, optical memory, digital...

Innovative Aluminum Flat Solar Collector
The most important feature of this solar collector is the technical solution where the heat-absorbing surface is the same as the heat-transferring surface, which results in the highest heat performance and efficiency. There is no mediatory unit between the heat-transferring surface of the absorber and the...
