Earth curvature line of sight
WebEarth curvature and atmospheric refraction are two primary systematic errors that must be taken into account when measurements become sufficiently long. Curvature and refraction affect any measurements dependent on an optical line of sight (LoS) or energy wave, which is quite a few. ... The red line is the original LoS at the 90°00'00" zenith ...

WebJul 26, 2024 · Phase retrieval wavefront sensing methods are now of importance for imaging quality maintenance of space telescopes. However, their accuracy is susceptible to line-of-sight jitter due to the micro-vibration of the platform, which changes the intensity distribution of the image. The effect of the jitter shows some stochastic properties and it is hard to …
