The invention discloses a two-particle time sequence coding ray camera and a use method thereof, and the two-particle time sequence coding ray camera comprises a center detector, an annular dual-mode coding pore plate, a signal processing analysis system, a rotating platform control system, a supporting platform and a rotating platform. According to the invention, the contradiction between the device sensitivity and the spatial resolution in the traditional time sequence coding camera design is solved to a great extent, the one-dimensional position resolution of the particle reaction is realized by reading out the signals at the two ends of the detector, the device sensitivity is improved by increasing the size of the detector, the spatial resolution is ensured, and the detection accuracy is improved. The method can be applied to detection and positioning imaging of an out-of-control radioactive source, and has very important application value in the fields of special nuclear material detection, nuclear diffu
