Abstract: A biocular display system is provided for use with a transmissive micro-LCD display and a biocular lens, where the biocular system includes a relay lens that can transfer a digital image from the transmissive micro-LCD display to a micro-resolution screen surface where a micro-diffusion surface is applied to a single planar transparent substrate that has a smooth surface on a side opposite the micro-diffusion surface, and the micro-diffusion surface has at least some surface features that can diffuse the light passing therethrough at greater than a 60-degree diffusion angle.

Abstract: A digital display for viewing images generated by a remote video source. Light collected by a lens is focused and passed through one polarizer filter and is focused through a digital device comprising an array of pixels of which each may be fitted with a micro lens. The light is passed through the digital device, then through a second polarizer filter. A relay lens which may alter image size, transfers the image to a micro-resolution screen surface whose surface features are as small as possible and preferably under 0.5 microns in size. The micro-resolution screen surface acts as a rear projection screen which, due to its structure, achieves near Lambertian illumination. A viewing lens is focused on the image plane of the micro-resolution screen surface for viewing by the user. In one embodiment, the digital device is an LCD that is transmissive and the viewing lens is a biocular lens. The source of the signals to be used to generate the images, may be a computer or a camera.

Abstract: A waterproof, large capacity film magazine is provided for use with an existing camera which includes outer magazine housing for sealably engaging an existing camera body and film handling apparatus disposed in the outer magazine for transporting film across a focal plane of the existing camera body without passing the film under, around, or through any element of the existing camera.

Abstract: An extended film magazine for an underwater camera is adapted to be attached to the camera in place of the rear door by a bezel means which provides watertight attachment between a housing of the magazine and the camera. The bezel means aligns and holds a first film holding cassette and a film take-up assembly having all of the operating components thereof, in the housing for easy access and loading. The bezel means also includes sealing means to effectively seal the magazine housing and the camera, and the film take-up assembly is mechanically coupled to the existing film transport mechanism of the camera to drive a take-up means held in this take-up assembly to move unexposed film from the film cassette, through the camera and onto the take-up means.
