A 28kHz-Resolution Acousto-Optic Spectrometer
Published online by Cambridge University Press: 04 August 2017
Abstract
A 28kHz resolution acousto-optic spectrometer has been established. The modulator is a TeO2 cell with off-axis acoustic slow shear wave. The convolution between the profiles of the modulator and the photodiode array was considered. Its velocity resolution is 0.07 kms−1 for 115 GHz CO molecular lines. The test observations were made by association with the 4-m mm-wave telescope in Australia. Some features of the CO lines in dark clouds have been seen more in detail.
