Pixel Level Stepped Filters, also known as Pixel Level Stepped Hyperspectral Filters, are specialized optical filters engineered to divide the field of view of an imaging system into distinct spectral bands using a stepped pattern. This design ensures that each spectral channel in the column direction is an integer multiple of the detector pixel size, while in the row direction, it matches the size of the detector imaging surface. This configuration provides full coverage of the detector imaging surface, enabling efficient filtering and capturing of all spectral information in the image.
