ABSTRACT:
A device detects the times of multiple explosions to within a microsecond thout the need for precise aiming. The device uses a linear array of photodetectors to detect light from the explosions. Each photodetector views a different area, so that explosions occurring in different areas are viewed by different photodetectors. To increase the sensitive area of each photodetector while keeping the device compact, the photodetectors are elongated in a direction orthogonal to the direction in which they are arrayed. A filter is used to transmit only the light produced at the beginning of each explosion.
