Abstract : Apparatus which corrects optical aberrations produced by an ogive shaped window on a laser seeker system. A holographic optical element is provided which breaks the received radiation, at the proper wavelength, into four components and focuses each component into a separate detector. The gain of each detector amplifier is adjusted according to the direction the gimbled seeker is pointed thus allowing the guidance control system to operate without offset even though the received radiation is aberrated by the ogive shaped window.
