Abstract

DC60 (17/09/44) A head-mounted virtual image display unit is equipped with a compact size. Weight and incorporated into the system High-performance optics That clearly demonstrates the ability to see through, shielding the sliding light may be incorporated. For those examples, when the ability to see through is not desirable, focus adjustments may be incorporated to allow the focus of the image, for example at a distance of approximately 18 inches to infinity. The adjustable headband may be Incorporated into which To fit the user's head Boom structure that can be bent May be included To facilitate fine-tuning of the optical assembly. Slider mechanism And ball joints may be incorporated to facilitate Adjust the position of the optical assembly. Cheap microphone Built-in may be incorporated to enable speech input by the user. A head-mounted virtual image display unit may It is used comfortably in combination. With glasses, safety glasses And provides useful images to the user without obstructing the picture of the surrounding environment. That appears satisfied In order to greatly increase the user acceptability The head-mounted virtual image display unit is equipped with a compact size.

Claims (6)

1. Compact vision system for video signal transmission For visibility by users The video signal is produced in accordance with Small display unit (1100) system which consists of When used together with such a small display unit The beam splitting prism (1400) was positioned close to the small display unit, the field lens (1200) was placed between the beam splitting prism and the microscopic display unit, the negative lens (1300) was placed between the field lens and the beam split prism. The reflected lens light (1500) is positioned close to the beam splitting prism on the side of the beam splitting prism in contrast to the smaller display unit, and the wavelet discs (1600) are positioned between the reflector lens and the prism, which separates the beam in which the prism. Separate beams, field lenses, negative lenses, reflection lenses and wavelength discs are arranged until the image signals are linearly polarized in accordance with the unit. Small displays (a) pass through the field and negative lenses (b) into the beam splitting prism. Most of the pass through the polarization surface of the beam splitting prism (c) passes through the disc that becomes circular polarized (d) reflected at the lens surface reflected back to the wavelet. Through the waves The second time became It is linearly polarized with the polarization direction rotated by 90 degrees in relation to the original linear polarization direction.
