Calculation of the scheme of recording a volume axial holographic optical element in the infrared region of the spectrum

Main parameters of the scheme of recording a volume axial holographic optical element (HOE) in the infrared region of the spectrum are calculated. The recording scheme is based on a modified scheme of the cyclic Hariharan–Sen interferometer. For the HOE 400 mm in diameter with a focal length of 800 mm, the calculated parameters of the recording scheme are presented that demonstrate that the diameter of the optical element is much less than the HOE diameter.
