An acousto-optic tunable filter ( AOTF) is electronically tunable spectral bandpass filter, which is based on the principle of acousto-optic interaction in an anisotropic medium. 声光可调滤光片(Acousto-optictunablefilter,AOTF)是一种窄带可调滤光片。它是根据声光作用原理制成的分光器件。
Based on the acousto-optic effect the sound wave in the medium is similar to a diffraction grating. 实验发现,根据声光效应,介质中的声波类似于衍射光栅。
The acousto-optic tunable filter ( AOTF) is a newfashioned prismatic element uses of acoustooptic effects in anisotropic medium. 声光可调滤波器(AOTF)是由各向异性介质中的声光相互作用研制而成的一种新型分光元件。
