Abstract

PURPOSE: To prevent the occurrence of a speckle noise and to view an excellent image with a little power consumption by modulating a laser light beam with a video signal so that scanning may be performed and directly forming the image on the retina of eyes through an optical system.
CONSTITUTION: The laser light beam emitted from an He-Ne laser 11 is con verged and made incident on an acoustooptical modulator AOM 13, then the intensity of the laser light is modulated with the signal of a video signal supply circuit 14. It is deflected at right angle by a reflection mirror 17. A filter 16 is a black filter. The cross-sectional shape of the beam is converted to an ellipti cal shape by cylindrical lenses 18, 19 and 20, made incident on an acoustooptical deflector AOD 21 and scanning is performed by a horizontal scanning signal supply circuit 22. Then, the cross-sectional shape of the beam is restored to be circular again by cylindrical lenses 23 and 24 and the plane of polarization in a vertical direction is converted to circular polarization of light by a #l/4 polarizing plate 25. A galvanometric mirror 26 is driven by a vertical scanning signal supply circuit 27 to perform vertical scanning, so that the light is directly made incident in the eye 28 through lenses 29 and 30.
