Angular resolution of LISA
LISA is a space-borne, laser-interferometric gravitational wave detector currently under study by the European Space Agency. We give a brief introduction about the main features of the detector, concentrating on its one-year orbital motion around the Sun. We show that the amplitude as well as the phase of a gravitational wave is modulated due to that motion, allowing us to extract information f...
متن کاملAngular Resolution of the LISA Gravitational Wave Detector
We calculate the angular resolution of the planned LISA detector, a space-based laser interferometer for measuring low-frequency gravitational waves from galactic and extragalactic sources. LISA is not a pointed instrument; it is an all-sky monitor with a quadrupolar beam pattern. LISA will measure simultaneously both polarization components of incoming gravitational waves, so the data will con...
متن کاملIntegrated High Resolution Focal-Plane Polarization Imager
The polarimetric vector is a more general descriptor of light than intensity information alone, and it contains physical information about the imaged objects in a scene that traditional intensity based sensors ignore. Polarimeters – devices that measure polarization – are used to extract physical features from an image such as specularities, occluding contours, and material properties. Scientis...
متن کاملHigh Resolution CCD Polarization Imaging Sensor
We present a novel polarization imaging sensor by monolithically integrating aluminum nanowire optical filters with an array of CCD imaging elements. The CCD polarization image sensor is composed of 1000 by 1000 imaging elements with 7.4m pixel pitch. The image sensor has a dynamic range of 65dB and signal-to-noise ratio of 45dB. The CCD array is covered with an array of pixel-pitch matched na...
متن کاملResolution to the B → φK ∗ polarization puzzle
We resolve the B → φK∗ polarization puzzle by postulating a smaller B → K∗ form factor A0 ≈ 0.3 and by adding penguin annihilation and nonfactorizable contributions from the perturbative QCD approach. If this explanation is correct, the modes governed by the B → K∗ form factors, such as B+ → K∗+K∗0 and B0 → K∗0K̄∗0, should exhibit similar polarization fractions. Our resolution is compared with o...
