  • The Fundamentals Of AOTF-Based Spectral Imaging And Polarimetry
    The Fundamentals Of AOTF-Based Spectral Imaging And Polarimetry

    Many hyperspectral imaging (HSi) systems use a diffraction grating to split up a line of an image into strips with different wavelengths and so build up a 3D image cube. While this push-broom process works well for capturing hyperspectral images where there is a built-in, one-dimensional relative movement between the camera and the object, there are many situations where band sequential imagers are more effective. This article explores the basics of acousto-optic tunable filter (AOTF) and polarimetric technology and discusses the advantages of using those approaches for hyperspectral imaging. By Alexandre Y. Fong and Jon Ward, Gooch & Housego
