Apparatus, system, and method for enabling eye-to-eye contact in video conferences. In general, the system and apparatus employ means for generating video images corresponding to real images that would be produced if a video camera were disposed at or behind a video display having a field of view directed toward a target object such as a participant. An image (either real, reflected, or holographic) is formed based on light reflected off of the target object, and object light corresponding to the image is received by the video camera, which produces a video signal containing the image. Typically, the means for generating the video images employs direct imaging, reflective imaging, or holographic imaging. The means for generating the video images are also configured in such a manner as to be substantially transparent to video conference participants viewing the display images on the video display. A similar configuration is deployed at two or more conference rooms, thereby enabling participants to communicate with one another using eye-to-eye contact.

The present invention is related to a curved surface, real image, laser-based rear projection display system. A plurality of translucent panel members are assembled into a spherical dome assembly. The panels have concave inner surfaces treated with an optical medium to create a diffusion surface onto which the projected visual image is displayed to a design eye point located within the dome. The laser-based projectors have a greatly expanded focal range as compared to conventional sources of illumination. This allows the curved panel members to remain in focus when the dome is moved as much as two (2) relative to the location of the laser projector.

A diagnostic and therapeutic contact lens is provided for use with biomicroscopes for the examination and treatment of structures of the eye. The lens comprises a contacting surface adapted for placement on the cornea of an eye, two reflecting surfaces, and a refracting surface. A light ray emanating from the structure of the eye enters the lens and contributes to the formation of a correctly oriented real image.

A light field microscope incorporating a lenslet array at or near the rear aperture of the objective lens. The microscope objective lens may be supplemented with an array of low power lenslets which may be located at or near the rear aperture of the objective lens, and which slightly modify the objective lens. The result is a new type of objective lens, or an addition to existing objective lenses. The lenslet array may include, for example, 9 to 100 lenslets (small, low-power lenses with long focal lengths) that generate a corresponding number of real images. Each lenslet creates a real image on the image plane, and each image corresponds to a different viewpoint or direction of the specimen.
