PASAT: pathfinder in solar adaptive telescope

Blog Article

In the forefront of quantitative solar physics research using large-aperture ground-based solar optical telescopes, high-contrast observation along with high-accuracy polarimetric measurement in the solar active region are required.In this paper, we propose a novel high-contrast imaging telescope construction weleda skin food 75ml best price with a 60 cm medium aperture, namely, the PAthfinder in Solar Adaptive Telescope (PASAT), in which a deformable secondary mirror is used as the adaptive optical correction device and a symmetrical optical path design is employed, leading to the least Muller matrix polarization instruments.The telescope can provide a high-resolution magnetic field with high accuracy for the solar active regions, as well as high-contrast images with a superior signal-to-noise ratio and photometric accuracy of the solar photosphere and chromosphere.These data will be directly used for a better understanding of the evolution and release of magnetic energy, which will help in improving space weather forecasting.Meanwhile, PASAT will accumulate the nitrile gloves in a bucket relevant techniques for constructing similar, larger solar telescopes in the future.
