Hang gliding simulation system with a stereoscopic display

A method for providing pupil forming simulated images of positional states controlled by a user of a simulation system with a programmed environment, comprising:

• utilizing at least two cathode ray tubes (CRTs) for providing left and right eye pupil forming images of simulated movement in said programmed environment;
• arranging at least two lenses arranged relative to said CRTs to focus the left and right eye pupil forming images;
• reflecting said left and right eye pupil forming images through a spherical mirror to left and right eyes, respectively, of the user;
• disposing a beamsplitter relative to said lenses to thereby superimpose said left and right eye pupil forming images and to transmit said pupil forming images to said spherical mirror for reflection to said left and right eyes of the user;
• and
• providing a fixed point of reference for the user with respect to the spherical mirror such that movement of the simulated images as seen by the user in the left and right eye pupil forming images does not require movement of the user's head.

A stereoscopic display system for providing pupil forming simulated images of positional states controlled by a user of a simulation system in a programmed environment, comprising:

• a first cathode ray tube (CRT) for providing a right eye pupil forming image of simulated movement in said programmed environment;
• a second CRT for providing a left eye pupil forming image of simulated movement in said programmed environment;
• a first lens which is located above a viewing plane defined by eyes of the user and a pair of pupil images, said first lens transmitting beams from the first CRT to a beamsplitter;
• a second lens which is located below the viewing plane, said second lens transmitting beams from a second CRT to the beamsplitter;
• the beamsplitter arranged relative to said first and second lenses to thereby superimpose and transmit said left and right eye pupil forming images;
• and
• the spherical mirror for receiving and reflecting said left and right eye pupil forming images from the beamsplitter to a left eye and a right eye, respectively, of the user.
