    摘要: A target plate (Z) according to the invention for positioning components, in particular pipes (R1, R2), has a holographic optical element as a holographic diffusor. By means of the diffusor, radiation striking the target plate (Z) in the form of a reference beam (RS) can be guided very accurately and virtually without loss into a defined solid angle region (dΩ). Furthermore, the diffusor may have stochastically distributed structures and thus illuminate the solid angle region (dΩ) homogeneously. By means of the target plate (Z), the visibility of the incident reference beam (RS) is increased, and the reference beam (RS) can also be detected independently of position.
