Аннотация:We developed two high-quality large-aperture acousto-optic tunable filter cells in TeO
2 with more than two octaves
spectral coverage for hyperspectral imaging applications from the visible to the midwave infrared: the first cell covers from 0.43 to 2.1 μm and the second from 0.69 to
4.0 μm . The key feature of these cells is a special design of two transducers
in tandem with a special bonding technique that results in such a wide spectral coverage with virtually no acoustic and electrical loss due to careful matching of both acoustic and electrical impedances. Each of these cells has high spectral transmission, as well as low power requirement. We discuss the design, characterization, and performance results for these cells.
