Tunable acousto-optical (AO) filter based imaging spectrometer based on the tunable acousto-optical (AO) filter is designed for the acquisition of data combining simultaneously both high spatial resolution and high spectral resolution. The tunable acousto-optical filter based imaging spectrometer is intended mostly for study the planets and the emission objects - planetary nebulae and Seyfert galaxies - to get images at different wavelengths.
Tunable acousto-optical (AO) filter based imaging spectrometer can be useful for study the variability of emission lines in AGNs (active galactic nuclei), such as Seyfert galaxies and quasars. The tunable acousto-optical (AO) filter based imaging spectrometer possesses very large optical input aperture and large optical angular aperture. Special optical geometry of the acousto-optical filter is used in order to keep the direction of the optical axis the same. These constructive features of the device provide easy way for its installation into the telescope because the complicated additional optics is not needed. The tunable acousto-optical filter based imaging spectrometer can be used with any typical f/12 - f/20 Cassegrain telescope and with any typical CCD camera. Computer-controlled two-channel driver system provides the potential capability for the correlation spectral analysis.
