materials that only pass the bands of interest or through prisms diffraction gratings or anti reflective coatings the mwir portion of incoming light is also detected by this fpa embodiment and the gaps created through the omission of every other pixel due to a combination of the waveband filter mask and roic circuitry are filled in by an extended range image processing technique of a type disclosed in u s patent application ser no 11 429 958 u2014 the contents of which are hereby incorporated by reference the mwir signal is detected through a standard fpa integration multiplexing technique depicted in fig2 b alternative embodiments of the inventive concept may employ different methods for separately processing the multiple types of input detected by a multi mode detector possible alternatives include charge injection devices digital roics any other variations of detection devices capable of providing multi channel analog output in addition to integrated image signal output fig4 a shows the imaging portion of an embodiment of a multi mode missile seeker device that provides both target imaging and target tracking capabilities using a sampled imaging output and a non sampled analog channel output the fpa 315 which contains both the detector with a patterned waveband filter and the roic with the added analog channel outputs is operatively connected to a controller 330 that governs the operating mode of the fpa 310 feeds in a power signal 305 and feeds in a timing signal 301 the controller also monitors fpa temperature and controls cooling of the fpa unit 320 the signal output of the fpa 325.
