This invention discloses an automatic target-reporting method and system for indoor and outdoor bullet shooting. It includes veiling sensor array, signal collection, coordinates computation and display parts. The basic cell array of the veiling sensor is composed of a linear light source L and corresponding receiving device. The linear light source L is composed of light-emitting diodes that are arranged in line. The receiving device S is formed by the end face of optical fiber. The veiling sensor is three-dimensional frame structure. Two parallel veiling are used together in the X and Y computed coordinate directions. Each of them has two V shaped veiling which form alpha angle with the two parallel veiling. Thus, they form the special veiling sensor array. Only four sets of veiling basic cell arrays can fulfill the three-dimensional no touch measurement of the bullet. It can give the exact location and speed of the bullet on the target. The rate of false reporting rate is low. It will not be interfered by adjacent target.

The present application demonstrates that both active substances and diagnostically effective substances can be introduced into biological cells, in particular blood cells, simultaneously. These multimodally altered cells can be found once again, in vivo and in vitro, using modern imaging methods. In addition to the diagnostic and active compound-carrier principles, they can serve as a form for administering the active substances in an accurately targeted manner.
