FIELD: physics.
SUBSTANCE: light screen is designed to determine flight coordinates of a bullet or a missile from the interruption of beams from two radiation sources fixed near photodetectors. The radiation sources are distinguished from the value of the output signal of the photodetectors, wherein each photodetector is optically interfaced with both radiation sources and is connected to two comparators which enable to determine which beam of the two radiation sources was interrupted relative the photodetector connected to it.
EFFECT: simple design of the light screen.
