A filtered multispectral multidetector imager, which comprises: (a) first prism means providing a first optical path for radiation therethrough; (b) second prism means proximately positioned adjacent to said first prism means for providing a second optical path for radiation therethrough, said first prism means and said second prism means having an air gap therebetween; (c) piezo electric transducer means operatively connected to said first prism means for reciprocally opening and closing said air gap intermediate said first and second prism means and thereby switching between said first optical path and said second optical path; (d) first array detector means in alignment with said first prism means for detecting radiation passing through said first prism means; (f) first substrate means for supporting said first array detector means; (g) second array detector means for detecting radiation reflected by said second prism means; (h) second substrate means for supporting said second array detector means, said second substrate means having a front and a rear surface; and (i) spectral filter array means operatively supported on said second substrate means intermediate said second prism means and said second detector means for providing a plurality of band pass filters for generation of a single frame multispectral image.
