AOTF Tunable Filters
AOTF Tunable Filters . Acousto optic tunable filters AOTF: Acousto-optic tunable filters (AOTFs) are solid state wavelength tunable optical filters. … Interactions of photons with these perturbations allow the AOTF to selectively diffract a single narrow-bandpass wavelength. The wavelength may be varied by changing the applied frequency.
