ABSTRACT:
A nonconducting, nonradiating remote communication system for use with medical research, diagnostic, and therapeutic instruments without disturbing the operation of those instruments, in which an image generator such as a CRT generates an image or stereo images to be viewed by a patient while the patient is being examined by the instrument. A fiber optic bundle relays the generated image to an eyeglass assembly worn by the patient. The eyeglass assembly comprises left and right image relay lens systems for relaying the images to the left and right eyes of the patient, and a mirror positioned between each relay lens system and the eye to reflect an image onto the eye. Each relay lens system can comprise a conventional relay lens system, or a graded index relay lens system, or a binary optic relay lens system. Each mirror can comprise a prism, or a pellicle mirror, a holographic mirror, or a binary optics mirror.
