Abstract
A target object () used for retroflexion of optical radiation comprises at least six triple prisms (p, p), combined to give a 360 degree reflector which can be arranged on a geodetic measuring pole (). The triple prisms (p, p) forming the 360 degree reflector are arranged in such a manner as to leave a clearance in the center of the 360 degree reflector for accommodating a section () of the measuring pole (). The prisms are also arranged in such a manner that the virtual images of the triple prism tips lie substantially in one plane perpendicular to a reference axis () that runs through the center of the 360 degree reflector and in parallel to the longitudinal direction of the measuring pole ().
