Tunable Filters (AOTF) | Gooch & Housego

In an acousto-optic tunable filter (AOTF), an RF drive frequency is applied to an acousto-optic material such as tellurium dioxide (TeO 2) to create a diffraction grating in which the refractive index of the crystal varies with position. As a coherent optical beam passes through the crystal, only a narrow band of frequencies will interfere ...
