The Laser Interferometer Space Antenna (LISA) and the Big Bang Observer (BBO) require angular sensing in their gravitational reference sensor (GRS), telescope pointing, and spacecraft control. The ...

Magnifying power is defined as the ratio between the dimensions of the image and the object. The process of magnification can occur in lenses, telescopes, microscopes and even in slide projectors.

Abstract: Cosmic magnification is due to the weak gravitational lensing of sources in the distant Universe by foreground large-scale structure leading to coherent changes in the observed number ...

This study aimed to assess the effects of different magnification systems on the angular deviations of the neck and trunk and the muscle activities of the upper back and neck during preclinical cavity ...
