    摘要： A scanning beam display controls the curvature of scanning light wave impinging on the eye to simulate image points of differing depth. To simulate an object at a far distance the generated light waves are flatter. To simulate closer objects, the light wave curvature increases. When changing the curvature of the light waves, the eye responds by altering its focus. The curvature of the light waves thus determines the apparent focal distance from the eye to the virtual object. To vary the curvature, either a variable focus lens or a variable index of refraction device is used. Alternatively, a moving point source is used. The generated apparent distance of a virtual object is correlated to a detected distance in a background field of view. Intensity of the virtual object is correlated to detected intensity of background light.

    摘要： A display device is achieved using a simplified optical system which generates an expanded exit pupil without compromising magnification or resolution. Modulated light from a source is converged toward a focal point by an optics subsystem. A scanning subsystem deflects the converging light, and thus the focal point, along a raster pattern to define an intermediate image plane. A lens array defines a surface which coincides with the image plane. The lens array includes a plurality of lenses and a polymer dispersed liquid crystal film. The film serves to spread incident light and thus form an expanded exit pupil.

    摘要： Methods of moving or vibrating cantilevered optical fibers of scanning fiber devices are disclosed. In one aspect, a method may include vibrating the cantilevered optical fiber at an initial frequency that is substantially displaced from a resonant frequency of the cantilevered optical fiber. Then, the frequency of vibration of the cantilevered optical fiber may be changed over a period of time toward the resonant frequency. Light may be directed through an end of the cantilevered optical fiber while the cantilevered optical fiber is vibrated.

    摘要： Light emitted from a virtual retinal display light source passes through a beamsplitter to a scanning subsystem and on to an eyepiece and the viewer's eye. Some of the light is reflected from the viewer's eye passing back along the same path. Such light however is deflected at the beamsplitter toward a photodetector. The reflected light is detected and correlated to the display scanner's position. The content of the reflected light and the scanner position for such sample is used to generate a map of the viewer's retina. Such map includes ‘landmarks’ such as the viewer's optic nerve, fovea, and blood vessels. The map of the viewer's retina is stored and used for purposes of viewer identification. The viewer's fovea position is monitored to track where the viewer is looking.
