Subject of study . Axial computer-generated hologram optical elements (CGHOEs) and laser holographic interferometry based on CGHOEs are studied. Aim of study . The aim of this review is to actualize the original technical solutions developed since the mid-1960s at all stages of the evolution of axial computer-generated hologram optics and laser holographic interferometry (as its derivative). Method . The study is based on the systematization and evaluation of a novel technology of forming periodic ruled structures in the thin working layer of a hologram using a diamond edge tool with a bicylindrical cutting edge. The study is primarily focused on the influence of the off-duty ratio, kinoform profile accuracy, congruence of the recorded structure, and resulting diffraction efficiency. Main results . The main stages of the origin, formation, and development of axial computer-generated hologram optics and laser holographic interferometry at JSC “NPO GIPO” are presented, along with promising options for their further practical implementation. The exceptionally high practical relevance of axial (Gabor-type) holographic testing schemes is demonstrated, highlighting the utility of using axial computer-generated holograms as optical references and null correctors. Several original interferometric system designs employing axial CGHOEs as optical compensators (null correctors), optical samples, and beam splitters are described. In addition, an unequal-arm Michelson interferometer is proposed for simulating the possible cosmological “aging” of light. Practical relevance . The results of this review contribute to the broader adoption of laser holographic interferometry, based on axial computer-generated hologram optics, in optoelectronic instrument engineering.
