Abstract:
1. An arrangement for electronically determining a shooting position on a shooting target, the arrangement comprising: light sources for transmitting light; photo-electric light receivers, structured and arranged to detect the light transmitted by the light sources, being arranged to form optical paths between the light sources and the light receivers, the optical paths being formed into at least two inter-crossing groups to define an optical screen arranged generally perpendicular to a shooting direction, wherein at least one optical path of each of the inter-crossing groups is at least temporarily interruptible by a projectile passing through the optical screen; at least one of a canvas-like or plate-like object arranged generally parallel to the optical screen; multiple acoustic transducers being arranged at a distance from each other for detecting an acoustic wave generatable by a projectile when shot through the at least one canvas-like or plate-like object; and an electronic evaluator structured and arranged to determine at least one of a pass-through position of the projectile in relation to the optical screen from signals received from the photo-electric light receivers and a pass-through position of a projectile in relation to the at least one canvas-like or plate-like object based on delay times detected by the multiple acoustic transducers of the acoustic wave generatable by the projectile being shot through the at least one canvas-like or plate-like object, wherein the arrangement, in the shooting direction, is structured so that a circular area definable within the optical screen is surrounded at least partially by an area of the at least one canvas-like or plate-like object in which the acoustic wave is generatable.
