Compressed sensing for next generation instruments
This document discusses the possibility of using compressed sensing techniques for measuring 2D spectro-polarimetric information using only one etalon and a...
Computed color indices and spectral shapes for individual stars are routinely compared with observations for essentially all spectral types, but absolute fluxes...
Concept of SPARC4: a simultaneous polarimeter and rapid camera in 4 bands
We present a summary of the concept design report of a new astronomical instrument: SPARC4, Simultaneous Polarimeter and Rapid Camera in 4 bands. SPARC4 will...
Concepts for Multi-wavelength Observations with the 1.5 m Solar Telescope GREGOR
The initial instrumentation of the 1.5 m solar telescope GREGOR on Tenerife will include a grating spectrograph with a spectro-polarimeter for the near infrared...
Concepts, laboratory, and telescope test results of the plenoptic camera as a wavefront sensor
The plenoptic camera has been proposed as an alternative wavefront sensor adequate for extended objects within the context of the design of the European Solar...
Conceptual design for the optomechanical systems of the New Robotic Telescope
The New Robotic Telescope (NRT) will be the largest fully robotic telescope in the world (4-m class). The primary mirror (M1) will be comprised of 18...
