Abstract : An optical proximity fuze is disclosed which has an improved response at close range with respect to a target. The fuze comprises a source of infrared radiation or visible light which is projected toward the target, and a receiver or detector which responds to radiation reflected from the target. An opaque field stop in front of the detector comprises multiple apertures for permitting only selected portions of the reflected radiation to reach the detector. The use of multiple apertures, rather than a singular large aperature, improves short range response of the fuze without increasing sensitivity of the fuze to aerosols.
