ABSTRACT:
A combination of a wobble-scan infrared (IR) seeker with an unscanned pul laser (L) seeker. Target IR&L energy is passed through a focusing lens system to a wedge filter which is mounted on a rotating gyro-stabilized platform. The filter separates the IR&L signals by reflecting the L signal from its top surface and the IR signal from its bottom, slanted surface. The L signal is focused on a quad cell detector and detected. The IR signal passes through this detector and is sent through a reticle which pulse-codes it. The pulse-coded IR energy is then focused by another lens on an IR detector.
