Method and apparatus for mounting a cathode ray tube for a heads-up display system.

摘要

A method and apparatus for a helmet mounted display with a cathode ray tube for mounting on the torso of the operator are disclosed. A disconnectable cable supplies an information bearing signal to a signal conditioning circuit for mounting on the torso of the operator and a low voltage signal to a high voltage supply also for mounting on the torso of the operator. The high voltage supply provides the necessary high voltage for the operation of the cathode ray tube. The signal conditioning circuit provides the horizontal and vertical deflection signals and a decoded and amplified information bearing signal to the cathode ray tube. The cathode ray tube converts the information bearing signal into CRT images. A reducer, adjacent to and facing the cathode ray tube display face, reduces these CRT images and presents them to an optical fiber bundle which in turn presents the reduced CRT images to an expander. The expander then enlarges the reduced CRT images into enlarged CRT images and presents the enlarged CRT images to the display optics in the helmet.
