摘要:
The device allows to compensate for the aberrations of the collimating and combining holographic optics by using a simplified scheme for the relay optics. Said relay optics comprises six lenses and a window; it is terminated at each end by a plane side and is disposed in a case. Said relay optics and the holographic optical element are determined taking into account average data for the thickness and curvature of the windshield. The accurate compensation for the windshield deviations is made at a closing glass plate whose thickness is varied. The Folding optical element is a simple reflecting plane mirror and has no correcting effect, which permits the translation along the optical axis of said relay optics and the cathode-ray tube generating the luminous image to be collimated.
