Atmosphere and Telescope Simulator

Atmosphere and Telescope Simulators for astronomy education, are used because time in science-worthy class telescopes are generally expensive and difficult to obtain. Telescope facilities are often uncomfortable for operators working for long periods of time. Researchers have expressed the need for a laboratory tool which could provide better and cheaper accessibility than a real telescope, and better characterization than computer simulations. A LED based illumination system in which five Galilean collimation systems have been used is reported on. It is part of a turbulence simulator for the evaluation of on ground telescopes instrumentation developed by INTA (optics) and LIDAX (opto-mechanics) [1] for the IAC called IACATS.
The IACATS instrument simulates a scene consisting of a set of different binary stars simulating the required angular separation between them, and their spectral characteristics. As a result, a visible and infrared multi-spectral illumination system has been integrated as a part of the turbulence simulator. A wave front sensor enables to evaluate the deformation that the phase plates, or the simulated turbulence, produce in the wave front coming from the illumination system and star simulator. Finally, a specific illumination system include different working wavelengths.
Different scenes are simulated from three main controlled parameters:
- Stars Light
- Atmospheric turbulences
- Telescope focal plane
