Abstract
A nose mounted obscuration fuze adapted to produce a near surface burst w the fuze approaches or starts to penetrate a target. The nose of the fuze is provided with a pair of relatively broad surfaces, one of which transmits light from a light source across an air gap forming a sensing area to a light detector in the other broad face of the sensor. The light transmission is measured between the two faces, and any significant change in light transmission through the air gap, such as when the fuze penetrates snow, activates the fuze.
