The Computed Tomographic Imaging Spectrometer based on metamaterial surface.

Computed Tomographic Imaging Spectrometer (CTIS) has the advantages of both computed tomography technology and snapshot spectroscopy and has potential applications in many fields. However, the development of CTIS has been limited by the volume issues of key components. In consideration of the compact structure of the metamaterial, an all-dielectric metamaterial array is studied as an alternative to optimize the structure of CTIS. The array can be used for snapshot-type optical imaging, with a wide working range of 550 nm ∼ 1000 nm. At the same time, the system design and simulation technology are studied by using the array, which provides a useful reference for the development of micro imaging spectrometer based on metamaterial. • Using metamaterials to realize the miniaturization of CTIS. • The metamaterial is first used to realize the CGH of CTIS. • The micro CTIS adapts to the lens size of the mobile phone.
