Development of device for optical measurement of spin rate of wind tunnel models [PDF]

Scientific Technical Review, 2018
In wind tunnel tests of free-spinning missile models it is of interest to measure the rotation rate of the models. As it is essential to provide free rotation of such models with minimum friction in the bearings, the instrumentation for measuring the ...

Quaternion Approach to the Measurement of the Local Birefringence Distribution in Optical Fibers

IEEE Photonics Journal, 2015
A method to structure the Jones quaternion utilizing Pauli matrices is proposed, improving the quaternion theory of polarization optics. It is proved that the Stokes quaternion is the double product of the Jones quaternion and its Hermitian transpose and

Forced Molecular Rotation in an Optical Centrifuge

Physical Review Letters, 2000
Intense linearly polarized light induces a dipole force that aligns an anisotropic molecule to the direction of the field polarization. Rotating the polarization causes the molecule to rotate. Using femtosecond laser technology, we accelerate the rate of rotation from 0 to 6 THz in 50 ps, spinning chlorine molecules from near rest up to angular ...

Miniature Twist/Rotation Fabry Perot Sensor Based on a Four-Core Fiber

Proceedings, 2018
This paper presents a miniature Fabry Perot twist/rotation sensor. The presented sensor consists of a single lead-in multicore fiber, which has four eccentrically positioned cores, a special asymmetrical microstructure, similar to a truncated cylinder ...

Encyclopedia of 2D β′‐In2Se3 Growth Using Chemical Vapor Deposition: The Effects of Synthesis Parameters Onto Material Quality

Advanced Engineering Materials, EarlyView.
A distinct semi‐confined inner‐tube chemical vapor deposition geometry enables reproducible, large‐area growth of phase‐pure 2D β′‐In2Se3 from InI + Se precursors. Engineering local vapor transport and optimizing precursor delivery and temperature–time conditions yield uniform continuous films.
