A hyperspectral imager includes a sensor array (36) and a filter array (38A). The sensor array is an array of individually addressable sensor elements (42), each element responsive to radiant energy received thereon. The filter array is arranged to filter the radiant energy en route to the sensor array. It includes an inhomogeneous tiling of first and second filter elements (44, 46, 48, 50), with the first filter element (44) transmitting radiant energy of an invisible wavelength band and rejecting radiant energy of a visible wavelength band. The second filter element (46, 48, 50) transmits radiant energy of the visible wavelength band and rejects radiant energy of the invisible wavelength band. |
