The emerging Fiber Optic Gyroscope (FOG) technology has demonstrated performance that can meet the requirements of current and future navigation and alignment systems. The performance comes at the cost of significant size and weight with resulting system packaging problems. The FOG Triad system proposed by System Engineering Sol., Inc. addresses this problem by configuring a compact nested 3-axi ...

For most cryogenically cooled systems, it is necessary to locate the cryocooler in close proximity to the cooled assemblies. This places highly demanding requirements on the cryocooler, its integration into the spacecraft, and subjects the cooled assembly to unwanted disturbances. Since the spacecraft radiator is usually remote from the cooled assemblies, a heavy conductive strap or heat pipe is ...

A novel technique for the processing of c-dopcd Yb-Er optical fiber cladding pumped lasers will be explored. If high power at 1550 nm is desired, it is advantageous to pump a c-dopcd Yb-Er fiber laser at 915 nm where there is a broad energy absorption band for Yb.. This energy is then resonantly transferred to the erbium co-dopant that provides the gain medium. in order to prevent back transfer fr ...

Performance of US students in mathematics and physics has been limited, partly because the traditional pedagogy relies on logical and linguistic methods of teaching, and students are primarily assessed on fact knowledge and discrete skills. Recent achievements in computer science provide revolutionary means for educational reform. Thus, use of the World Wide Web and Java - a package of a new obj ...

N/A

Superconducting light modulator is proposed which uses the physical properties of superconductors to greatly increase the transmission capacity of currently installed fiber optic lines Increased transmission capacity is required to make new services, such as video-on-demand, widely available at a reasonable cost The key inhibitor of fiber transmission capacity is the rate at which optical data can ...
