Electromagnetic wave transmission filters and electromagnetic cameras including the same

摘要

An electromagnetic wave transmission filter may include a substrate and one or more coils. The one or more coils may be at least partly disposed in an opening through the substrate. An electromagnetic camera may include an electromagnetic wave detector array, including a plurality of detector cells for detecting electromagnetic waves, and an electromagnetic wave transmission filter disposed in front of the electromagnetic wave detector array to provide each of the detector cells with an electromagnetic wave of a certain wavelength. The electromagnetic wave transmission filter may includes a substrate and a plurality of coils. At least one of the plurality of coils may be at least partly disposed in each of a plurality of openings through the substrate.
