We report on the acousto-optic spectral imaging system designed for speckle imaging
observations and interferometry. The setup is based on a non-collinear paratellurite
acousto-optic tunable filter (AOTF). Breadboard prototype of the system with an in-house
fabricated AOTF has been designed and commissioned. The prototype spectral range covers
the band from 3600 to 5800 A. Arbitrary spectral transmission function synthesis of
the AOTF was applied. The AOTF spectral transmission bandwidth is programmable in
the range from 44 to 875 cm(-1) (12.5-250 A at the wavelength of 5050 angstrom. The
AOTF is synchronized with the CCD readout and can be used as a global electronic shutter
with on/off switching time of 12 mu s. The exposure is adjusted as any integer multiple
of 4.5 mu s.
