Development of Sodium Lidar for Spaceborne Missions
The metal layers at mesospheric altitudes are excellent tracers of neutral atmosphere dynamics, and have been used since the 1960s to study the chemistry and dynamics of the mesosphere. Ablation from meteors is believed to be the chief source of metals such as Na, Mg, K, Fe, and Ca in the middle...
Briefs: Photonics/Optics
A method was developed for concurrently measuring bending and twisting along an optical fiber using only the properties of light guided within the fiber. The method exploits polarization-dependent...

Dual-Field-of-View Multiband Optics
Multi-spectral-band systems are steadily emerging as a desired feature in a camera system. Each spectral band offers different image characteristics. Shorter-wavelength spectral bands provide the potential for better resolution due to the smaller impact of diffraction on the size of the optics blur. This means...
