The central element of the Stanford relativity experiment is a cryogenic gyroscope with a performance in space many orders of magnitude superior to that of conventional earth-boiind devices. In the early pllases of the program, a great deal of thought wa? given t o the problem of achieving the performance goal, and an entirely new gyro concept was developed by William Fairbank and Francis Everi...

Fiber-laser sensors have potential advantages over conventional fiber-optic interferometric sensors owing to their simplicity in both optical configuration and electronic signal processing." A fiber ring laser is a good candidate for rotation-rate sensing because of the same advantages, and such a fiber-ring-laser gyroscope was demonstrated by use of Brillouin gain in the fiber.4'5 The Brilloui...

In this paper, an Adaptive Neuro Fuzzy Inference System (ANFIS) based control is proposed for the tracking of a Micro-Electro Mechanical Systems (MEMS) gyroscope sensor. The ANFIS is used to train parameters of the controller for tracking a desired trajectory. Numerical simulations for a MEMS gyroscope are looked into to check the effectiveness of the ANFIS control scheme. It proves that the sy...

In this study a solid dispersion and a physical mixture of cilazapril (CIL) with a biopolymer - polyvinylpyrrolidone (PVP) as a carrier were prepared so as to investigate the effect of PVP on the stability of CIL. CIL is unstable in solid state and decomposes rapidly under humid conditions. It requires stabilization to ensure safety of its use. The studied CIL/PVP formulations were prepared by ...

Gyroscopes are instruments capable of sensing changes in their inertial orientation. A gyroscope has one or more sensitive axis and can measure a rotation around them. They are usually mechanical devices that employ a rapid spinning mass to detect the inertial variations. Satellites usually have gyroscopes in the Attitude and Orbit Control System as attitude (orientation) sensors that measure a...

We demonstrate an efficient dynamical amplification of phase conjugation in the gain medium of a diode-pumped Nd(3+)YVO4 solid-state laser via excitation of its relaxation oscillations. Consequently, enhancement in the modulated amplitude of the phase conjugate wave is observed with up to +30 dB compared to the classical homodyne approach.

170 Gbit/s data transmission, microring lasers operating across the telecom C-band, and narrow-linewidth distributed-feedback lasers in Al2O3:Er waveguides on silicon, as well as amplifiers and continuous-wave lasers in Nd-doped polymer waveguides on silicon are presented. OCIS codes: (130.3130) Integrated Optics Materials; (140.4480) Optical Amplifiers; (140.5680) Rare Earth and Transition Met...

We present the generation of a picosecond polarized supercontinuum in highly birefringent multimodal microstructured fiber. The initial steps of the spectral broadening are dominated by intermodal four-wave mixing controlled by the specific fiber design. Using a low repetition rate ultra-stable solid state laser, a pulse train well-suited for versatile time-domain fluorescence lifetime imaging ...
