The study is in the general context of optical devices for communications and spectral analysis of optical signals with a particular focus on improving the performance of acoustooptic filters.

Acousto-optic tunable filters (AOTFs) are among the technologies commonly used in hyperspectral imagers. Once the fabrication of an acousto-optic filter is completed, its wavelength transmission function, particularly its selectivity, is fixed.
