Title: MEASURING FRAME FOR OPTICALLY ASCERTAINING A PERFORATION POSITION IN A CONTACTLESS MANNER, AND CORRESPONDING MEASUREMENT METHOD
Abstract:
The invention relates to a measuring frame (106) for optically ascertaining a perforation position of a projectile (134) through a target surface (102) in a contactless manner. In addition, the invention relates to a corresponding measurement and analysis method. The invention further relates to a display system which uses at least one such measuring frame (106). The measuring frame comprises at least one first (120) radiation source for emitting a first diverging radiation field, at least one second radiation source for emitting a second diverging radiation field, said first and second radiation fields intersecting at an angle on a plane transverse to a perforation direction, and at least one first (126) and at least one second (126') optical receiving device, which are paired with the at least one first and second radiation source, respectively. Each of the optical receiving devices has an array of optical receiving elements which can be analyzed such that a spatially extended shading position resulting from the projectile to be detected is determined.
