Abstract: Method and apparatus whereby instantly derived emissions of RGB tri-stimulus optical hues are processed into an isotropic field form of radiation for directed transmission through a selected imaging point of an electro-optical imaging screen as a unique point-hue pixel or radiant beam portion of an optical composition being imaged. Embodiments of the invention provide for video or other continuous imaging of contiguous pixels from electrical or optical data source signals. A preferred embodiment of the invention provides for a solid-state flat panel display.

Abstract: An apparatus for measuring refractive properties of transmissive elements such as ophthalmic lenses, including a mirror or deflective surface supported for adjustable movement in X and Y directions in order to deflect a light or other beam onto a detector which provides an output proportional to the deviation of the deflected beam from a null point when a lens or other transmissive element is positioned in the beam path; the output being arranged to drive a pair of servomotors, each coupled to a potentiometer connected to electrical circuits for indicating the position of the mirror or deflective surface in the X and Y directions and in conjunction with the light detector output, to return the deflected beam to the null point; simultaneously varying the resistance of the coupled potentiometers whereby the voltage output of the electrical circuits indicate refractive properites of the lens/transmissive elements.
