Experimental Study of Optical Characteristics of an Acousto-Optic Filter in a Wavelength Interval of 450–1700 nm
An acousto-optic (AO) tunable filter based on a paratellurite (TeO2) crystal with two piezoelectric transducers that provides arbitrary spectral addressing in a wavelength interval of 450–1700 nm is developed. Th...

Tunable Acousto-Optic Filter for the 450–900 and 900–1700 nm Spectral Range
The problem of creating an acousto-optic (AO) tunable filter, which allows us to obtain high-quality spectral images both in the visible and near-infrared ranges, is studied. Based on the analysis of the wide-...
