A laser-based infrared countermeasure (IRCM) system is disclosed. The IRCM system includes a set of receive optics, a dichroic filter, first and second detectors, a lens module and a laser. Receive optics are configured to receive optical information. The lens module reflects the optical information from the receive optics to the dichroic filter. The dichroic filter selectively splits the optical information to the first and second detectors. The first and second detectors, each of which is formed by a single-pixel detector, detects a potential missile threat from the optical information. Based on information collected by the first and second detectors, the laser sends laser beams to neutralize any missile threat.
