Abstract

A ballistic detection system includes one or more light sources configured to transmit collimated light through a detection area; a receiver array arranged with respect to the detection area to receive the collimated light in multiple side-by-side channels, the receiver array including (i) light detectors corresponding to the multiple side-by-side channels, and (ii) lenses arranged to focus respective portions of the collimated light, which has transited the detection area, onto respective ones of the light detectors corresponding to the multiple side-by-side channels; and a ballistics analysis computer coupled with the receiver array and programmed to identify a location of a projectile that passes through the detection area by performing ratiometric comparison of signal data from the light detectors, the signal data corresponding to fractional blockage, by the projectile, of the collimated light in one or more of the multiple side-by-side channels.
