Experience of computer generated holograms (CGH) application for testing, alignment, and positioning of astronomical and space mirrors aspherical surfaces

JSC LZOS successfully applies Computer Generated Holograms (CGH) for testing of on- and off-axis surfaces of largedimensioned optical components, for their alignment with respect to interferometer, for defining of aspherical surface optical vertex position with respect to the geometrical center, for optical systems alignment. All this allows producing of large-dimensioned aspherical on- and off-axis astronomical and space mirrors with high accuracy.
