ABSTRACT:
Dichroic mirrors employed in an optical seeker system to achieve spectral scrimination. The dichroic mirrors are aligned so as to produce a reticle phase difference between different wavelengths of reflected optical energy. Background optic energy is spectrally balanced so no net guidance is given to the seeker.
