Paper Abstract

After point out the principles of the acousto-optic spectrometer (AOS) some questions about channels number and the AOS measurements uncertainties are discussed. To overcome the limits imposed by the acoustic attenuation and velocity one low cost LiNbO3 acousto-electro-optic interaction configuration with high channels number possibilities is proposed. Taking the turbulence and temperature effects on measurements uncertainties together it was established a criteria to use the spectroemter during for radio astronomy observations with lower uncertainties and costs.
