Description
Technical Field
The invention relates to a light curtain electronic target technology, in particular to a directional light path protection device and a light interference resistant light curtain electronic target system.
Background
The light curtain electronic target generally forms a quadrilateral optical detection coordinate plane through a plurality of transmitters and a plurality of receiver arrays. For example, one emitter is arranged at the lower left corner of the quadrilateral (emitting light to the upper right) and the other emitter is arranged at the lower right corner of the quadrilateral (emitting light to the upper left), the emission angles of both emitters being 90 degrees, each emitter being responsible for a complete sector of 90 degrees. The top left-emitting ray can represent the same coordinate parameter and the top right-emitting ray can represent another coordinate parameter. For any impact point on the optical detection coordinate plane, the coordinate value of the impact point can be determined by the parameter values of the two coordinate parameters. The inventor finds that the receivers in the receiver array have mutually different and strictly-directed receiving light paths, but the front part of the light receiving surface of the whole receiver array is not protected by the light path, and is directly of a slit structure, so that the capability of resisting external light interference is poor, and the target scoring precision and the target scoring efficiency of the target drone are adversely affected.
