Holographic testing canal for large optical systems testing and alignment

The results of efforts concerning the creation of a testing system of the wavefront deformations in the telescope optical highway based on the use of the holographic optical element (HOE) are presented. The paraxial analysis of the HOE recording and the work of the testing canal are given. The solution of the non-determinacy problem of the testing results is described. Mathematical modeling of the holographic testing scheme and its correlation with telescope performance are made in frames of geometrical and wave optics.
