AMMUNITION WITH SURFACE-MOUNTED LIGHT-SETTABLE PICKUP ARRANGEMENT FOR DIGITAL MEMORY STORAGE

A projectile having a light-settable photodetector pickup assembly, in the form of a plurality of photovoltaic cell units, circumferentially mounted on the annular surface of the projectile, and also having an angular-position-indicating index reflector on the surface thereof. Each discrete photovoltaic cell unit is electrically connected with an electrical signal storage unit which is activated as a function of light acting on the respective photovoltaic cell unit associated therewith. A further photovoltaic cell unit is preferably provided as a source of energy for storage unit and/or logic or other circuit of operation.
