US12298107 - Semi-active laser seeker for miniature, laser-guided missile systems

The patent describes a semi-active laser seeker head designed for miniature, laser-guided missile systems, featuring a housing that encloses an inner chamber and a lens element that captures electromagnetic radiation. It includes a convex body that focuses the radiation onto a filter, which then selectively transmits the focused signals to a multi-channel sensor based on specific wavelength criteria.

Claim 1

1. A semi-active laser seeker head for miniature, laser-guided missile systems comprising a housing ( 20 ) limiting an inner chamber ( 23 ); a laser-permeable, a transparent lens element ( 40 ) that is seated in a gap ( 26 ) of the housing ( 20 ) reaching the inner chamber ( 23 ) so as to receive electromagnetic radiation, characterized in that, the laser seeker head comprises; a body ( 44 ) that has a convex surface ( 42 ) on which the lens element ( 40 ) is completely seated in the gap ( 26 ) on one hand and that extends into the inner chamber ( 23 ) on the other hand; and a filter ( 52 ) that directly receives the electromagnetic radiation, which is focused by said convex surface ( 42 ), from the body ( 44 ) that lies before and selectively transfers the electromagnetic radiation to a multi-channel sensor ( 56 ) arranged at the rear portion thereof based on a predetermined wavelength threshold.
