A Polarization Pursuers’ Guide
We calculate the detectability of the polarization of the cosmic microwave background (CMB) as a function of the sky coverage, angular resolution, and instrumental sensitivity for a hypothetical experiment. We consider the gradient component of the polarization from density perturbations (scalar modes) and the curl component from gravitational waves (tensor modes). We show that the amplitude (a...

We calculate the detectability of the polarization of the cosmic microwave background ~CMB! as a function of the sky coverage, angular resolution, and instrumental sensitivity for a hypothetical experiment. We consider the gradient component of the polarization from density perturbations ~scalar modes! and the curl component from gravitational waves ~tensor modes!. We show that the amplitude ~a...
متن کاملImproving sodium laser guide star brightness by polarization switching.
Optical pumping with circularly polarized light has been used to enhance the brightness of sodium laser guide star. But the benefit is reduced substantially due to the precession of sodium atoms in geomagnetic field. Switching the laser between left and right circular polarization at the Larmor frequency is proposed to improve the return. With ESO's laser guide star system at Paranal as example...
متن کاملLinear Differential Game With Two Pursuers and One Evader
The purpose of this paper is to compute two on one differential game No Escape Zones (NEZ) [8]. The main objective (over the scope of this paper) consists in designing suboptimal strategies in many on many engagements. 1x1 NEZ and 2x1 NEZ are components involved in suboptimal approaches we propose (i.e. “Moving Horizon Hierarchical Decomposition Algorithm” [6]). Several specific two pursuers on...
متن کاملEnhancing LCD Optical Efficiency with a Linearly Polarized Backlight and Polarization-preserving Light Guide Plate
We propose a new polarization-preserving edge-lit light guide plate (LGP) based on total internal reflection. Our simulation results show that such a LGP exhibits several attractive features: 1.54X higher polarization efficiency, 2.4X higher on-axis luminance, and no need for a brightness enhancement film. When integrated with a linearly polarized LED array, the LCD optical efficiency can be en...
